+"""Implements a number of Python exceptions which can be raised from within
+a view to trigger a standard HTTP non-200 response.
+
+Usage Example
+-------------
+
+.. code-block:: python
+
+    from werkzeug.wrappers.request import Request
+    from werkzeug.exceptions import HTTPException, NotFound
+
+    def view(request):
+        raise NotFound()
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except HTTPException as e:
+            return e
+
+As you can see from this example those exceptions are callable WSGI
+applications. However, they are not Werkzeug response objects. You
+can get a response object by calling ``get_response()`` on a HTTP
+exception.
+
+Keep in mind that you may have to pass an environ (WSGI) or scope
+(ASGI) to ``get_response()`` because some errors fetch additional
+information relating to the request.
+
+If you want to hook in a different exception page to say, a 404 status
+code, you can add a second except for a specific subclass of an error:
+
+.. code-block:: python
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except NotFound as e:
+            return not_found(request)
+        except HTTPException as e:
+            return e

+Application Dispatcher
+======================
+
+This middleware creates a single WSGI application that dispatches to
+multiple other WSGI applications mounted at different URL paths.
+
+A common example is writing a Single Page Application, where you have a
+backend API and a frontend written in JavaScript that does the routing
+in the browser rather than requesting different pages from the server.
+The frontend is a single HTML and JS file that should be served for any
+path besides "/api".
+
+This example dispatches to an API app under "/api", an admin app
+under "/admin", and an app that serves frontend files for all other
+requests::
+
+    app = DispatcherMiddleware(serve_frontend, {
+        '/api': api_app,
+        '/admin': admin_app,
+    })
+
+In production, you might instead handle this at the HTTP server level,
+serving files or proxying to application servers based on location. The
+API and admin apps would each be deployed with a separate WSGI server,
+and the static files would be served directly by the HTTP server.

+X-Forwarded-For Proxy Fix
+=========================
+
+This module provides a middleware that adjusts the WSGI environ based on
+``X-Forwarded-`` headers that proxies in front of an application may
+set.
+
+When an application is running behind a proxy server, WSGI may see the
+request as coming from that server rather than the real client. Proxies
+set various headers to track where the request actually came from.
+
+This middleware should only be used if the application is actually
+behind such a proxy, and should be configured with the number of proxies
+that are chained in front of it. Not all proxies set all the headers.
+Since incoming headers can be faked, you must set how many proxies are
+setting each header so the middleware knows what to trust.

+        })
+
+    The contents of the folder ``./shared`` will now be available on
+    ``http://example.com/shared/``.  This is pretty useful during development
+    because a standalone media server is not required. Files can also be
+    mounted on the root folder and still continue to use the application because
+    the shared data middleware forwards all unhandled requests to the
+    application, even if the requests are below one of the shared folders.
+
+    If `pkg_resources` is available you can also tell the middleware to serve
+    files from package data::
+
+        app = SharedDataMiddleware(app, {
+            '/static': ('myapplication', 'static')
+        })
+
+    This will then serve the ``static`` folder in the `myapplication`
+    Python package.
+
+    The optional `disallow` parameter can be a list of :func:`~fnmatch.fnmatch`
+    rules for files that are not accessible from the web.  If `cache` is set to
+    `False` no caching headers are sent.
+
+    Currently the middleware does not support non-ASCII filenames. If the
+    encoding on the file system happens to match the encoding of the URI it may
+    work but this could also be by accident. We strongly suggest using ASCII
+    only file names for static files.
+
+    The middleware will guess the mimetype using the Python `mimetype`
+    module.  If it's unable to figure out the charset it will fall back
+    to `fallback_mimetype`.
+
+    :param app: the application to wrap.  If you don't want to wrap an
+                application you can pass it :exc:`NotFound`.
+    :param exports: a list or dict of exported files and folders.
+    :param disallow: a list of :func:`~fnmatch.fnmatch` rules.
+    :param cache: enable or disable caching headers.

+    :param fallback_mimetype: The fallback mimetype for unknown files.
+
+    .. versionchanged:: 1.0
+        The default ``fallback_mimetype`` is
+        ``application/octet-stream``. If a filename looks like a text
+        mimetype, the ``utf-8`` charset is added to it.

+"""When it comes to combining multiple controller or view functions
+(however you want to call them) you need a dispatcher. A simple way
+would be applying regular expression tests on the ``PATH_INFO`` and
+calling registered callback functions that return the value then.
+
+This module implements a much more powerful system than simple regular
+expression matching because it can also convert values in the URLs and
+build URLs.
+
+Here a simple example that creates a URL map for an application with
+two subdomains (www and kb) and some URL rules:
+
+.. code-block:: python
+
+    m = Map([
+        # Static URLs
+        Rule('/', endpoint='static/index'),
+        Rule('/about', endpoint='static/about'),
+        Rule('/help', endpoint='static/help'),
+        # Knowledge Base
+        Subdomain('kb', [
+            Rule('/', endpoint='kb/index'),
+            Rule('/browse/', endpoint='kb/browse'),
+            Rule('/browse//', endpoint='kb/browse'),
+            Rule('/browse//', endpoint='kb/browse')
+        ])
+    ], default_subdomain='www')
+
+If the application doesn't use subdomains it's perfectly fine to not set
+the default subdomain and not use the `Subdomain` rule factory. The
+endpoint in the rules can be anything, for example import paths or
+unique identifiers. The WSGI application can use those endpoints to get the
+handler for that URL.  It doesn't have to be a string at all but it's
+recommended.
+
+Now it's possible to create a URL adapter for one of the subdomains and
+build URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.build("kb/browse", dict(id=42))
+    'http://kb.example.com/browse/42/'
+
+    c.build("kb/browse", dict())
+    'http://kb.example.com/browse/'
+
+    c.build("kb/browse", dict(id=42, page=3))
+    'http://kb.example.com/browse/42/3'
+
+    c.build("static/about")
+    '/about'
+
+    c.build("static/index", force_external=True)
+    'http://www.example.com/'
+
+    c = m.bind('example.com', subdomain='kb')
+
+    c.build("static/about")
+    'http://www.example.com/about'
+
+The first argument to bind is the server name *without* the subdomain.
+Per default it will assume that the script is mounted on the root, but
+often that's not the case so you can provide the real mount point as
+second argument:
+
+.. code-block:: python
+
+    c = m.bind('example.com', '/applications/example')
+
+The third argument can be the subdomain, if not given the default
+subdomain is used.  For more details about binding have a look at the
+documentation of the `MapAdapter`.
+
+And here is how you can match URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.match("/")
+    ('static/index', {})
+
+    c.match("/about")
+    ('static/about', {})
+
+    c = m.bind('example.com', '/', 'kb')
+
+    c.match("/")
+    ('kb/index', {})
+
+    c.match("/browse/42/23")
+    ('kb/browse', {'id': 42, 'page': 23})
+
+If matching fails you get a ``NotFound`` exception, if the rule thinks
+it's a good idea to redirect (for example because the URL was defined
+to have a slash at the end but the request was missing that slash) it
+will raise a ``RequestRedirect`` exception. Both are subclasses of
+``HTTPException`` so you can use those errors as responses in the
+application.
+
+If matching succeeded but the URL rule was incompatible to the given
+method (for example there were only rules for ``GET`` and ``HEAD`` but
+routing tried to match a ``POST`` request) a ``MethodNotAllowed``
+exception is raised.

+        following things can then happen:
+
+        - you receive a `NotFound` exception that indicates that no URL is
+          matching.  A `NotFound` exception is also a WSGI application you
+          can call to get a default page not found page (happens to be the
+          same object as `werkzeug.exceptions.NotFound`)
+
+        - you receive a `MethodNotAllowed` exception that indicates that there
+          is a match for this URL but not for the current request method.
+          This is useful for RESTful applications.
+
+        - you receive a `RequestRedirect` exception with a `new_url`
+          attribute.  This exception is used to notify you about a request
+          Werkzeug requests from your WSGI application.  This is for example the
+          case if you request ``/foo`` although the correct URL is ``/foo/``
+          You can use the `RequestRedirect` instance as response-like object
+          similar to all other subclasses of `HTTPException`.
+
+        - you receive a ``WebsocketMismatch`` exception if the only
+          match is a WebSocket rule but the bind is an HTTP request, or
+          if the match is an HTTP rule but the bind is a WebSocket
+          request.
+
+        - you get a tuple in the form ``(endpoint, arguments)`` if there is
+          a match (unless `return_rule` is True, in which case you get a tuple
+          in the form ``(rule, arguments)``)
+
+        If the path info is not passed to the match method the default path
+        info of the map is used (defaults to the root URL if not defined
+        explicitly).
+
+        All of the exceptions raised are subclasses of `HTTPException` so they
+        can be used as WSGI responses. They will all render generic error or
+        redirect pages.
+
+        Here is a small example for matching:

+        ('index', {})
+        >>> urls.match("/downloads/42")
+        ('downloads/show', {'id': 42})
+
+        And here is what happens on redirect and missing URLs:

+        >>> urls.match("/downloads")
+        Traceback (most recent call last):
+          ...
+        RequestRedirect: http://example.com/downloads/

+
+        The `build` function also accepts an argument called `force_external`
+        which, if you set it to `True` will force external URLs. Per default
+        external URLs (include the server name) will only be used if the

+        raised.
+
+        The build method accepts an argument called `method` which allows you

+    """A Rule represents one URL pattern.  There are some options for `Rule`
+    that change the way it behaves and are passed to the `Rule` constructor.
+    Note that besides the rule-string all arguments *must* be keyword arguments
+    in order to not break the application on Werkzeug upgrades.
+
+    `string`
+        Rule strings basically are just normal URL paths with placeholders in
+        the format ```` where the converter and the
+        arguments are optional.  If no converter is defined the `default`
+        converter is used which means `string` in the normal configuration.
+
+        URL rules that end with a slash are branch URLs, others are leaves.
+        If you have `strict_slashes` enabled (which is the default), all
+        branch URLs that are matched without a trailing slash will trigger a
+        redirect to the same URL with the missing slash appended.
+
+        The converters are defined on the `Map`.
+
+    `endpoint`
+        The endpoint for this rule. This can be anything. A reference to a
+        function, a string, a number etc.  The preferred way is using a string
+        because the endpoint is used for URL generation.
+
+    `defaults`
+        An optional dict with defaults for other rules with the same endpoint.
+        This is a bit tricky but useful if you want to have unique URLs::
+
+            url_map = Map([
+                Rule('/all/', defaults={'page': 1}, endpoint='all_entries'),
+                Rule('/all/page/', endpoint='all_entries')
+            ])
+
+        If a user now visits ``http://example.com/all/page/1`` they will be
+        redirected to ``http://example.com/all/``.  If `redirect_defaults` is
+        disabled on the `Map` instance this will only affect the URL
+        generation.
+
+    `subdomain`
+        The subdomain rule string for this rule. If not specified the rule
+        only matches for the `default_subdomain` of the map.  If the map is
+        not bound to a subdomain this feature is disabled.
+
+        Can be useful if you want to have user profiles on different subdomains
+        and all subdomains are forwarded to your application::
+
+            url_map = Map([
+                Rule('/', subdomain='', endpoint='user/homepage'),
+                Rule('/stats', subdomain='', endpoint='user/stats')
+            ])
+
+    `methods`
+        A sequence of http methods this rule applies to.  If not specified, all
+        methods are allowed. For example this can be useful if you want different
+        endpoints for `POST` and `GET`.  If methods are defined and the path
+        matches but the method matched against is not in this list or in the
+        list of another rule for that path the error raised is of the type
+        `MethodNotAllowed` rather than `NotFound`.  If `GET` is present in the
+        list of methods and `HEAD` is not, `HEAD` is added automatically.
+
+    `strict_slashes`
+        Override the `Map` setting for `strict_slashes` only for this rule. If
+        not specified the `Map` setting is used.
+
+    `merge_slashes`
+        Override :attr:`Map.merge_slashes` for this rule.
+
+    `build_only`
+        Set this to True and the rule will never match but will create a URL
+        that can be build. This is useful if you have resources on a subdomain
+        or folder that are not handled by the WSGI application (like static data)
+
+    `redirect_to`
+        If given this must be either a string or callable.  In case of a
+        callable it's called with the url adapter that triggered the match and
+        the values of the URL as keyword arguments and has to return the target
+        for the redirect, otherwise it has to be a string with placeholders in
+        rule syntax::
+
+            def foo_with_slug(adapter, id):
+                # ask the database for the slug for the old id.  this of
+                # course has nothing to do with werkzeug.
+                return f'foo/{Foo.get_slug_for_id(id)}'
+
+            url_map = Map([
+                Rule('/foo/', endpoint='foo'),
+                Rule('/some/old/url/', redirect_to='foo/'),
+                Rule('/other/old/url/', redirect_to=foo_with_slug)
+            ])
+
+        When the rule is matched the routing system will raise a
+        `RequestRedirect` exception with the target for the redirect.
+
+        Keep in mind that the URL will be joined against the URL root of the
+        script so don't use a leading slash on the target URL unless you
+        really mean root of that domain.
+
+    `alias`
+        If enabled this rule serves as an alias for another rule with the same
+        endpoint and arguments.
+
+    `host`
+        If provided and the URL map has host matching enabled this can be
+        used to provide a match rule for the whole host.  This also means
+        that the subdomain feature is disabled.
+
+    `websocket`
+        If ``True``, this rule is only matches for WebSocket (``ws://``,
+        ``wss://``) requests. By default, rules will only match for HTTP
+        requests.
+
+    .. versionchanged:: 2.1

+        Can be a domain, IPv4 or IPv6 address, or file path starting
+        with ``unix://`` for a Unix socket.
+    :param port: The port to bind to, for example ``8080``. Using ``0``
+        tells the OS to pick a random free port.
+    :param application: The WSGI application to run.
+    :param use_reloader: Use a reloader process to restart the server
+        process when files are changed.

+    :param extra_files: The reloader will watch these files for changes
+        in addition to Python modules. For example, watch a
+        configuration file.
+    :param exclude_patterns: The reloader will ignore changes to any
+        files matching these :mod:`fnmatch` patterns. For example,
+        ignore cache files.
+    :param reloader_interval: How often the reloader tries to check for
+        changes.
+    :param reloader_type: The reloader to use. The ``'stat'`` reloader
+        is built in, but may require significant CPU to watch files. The
+        ``'watchdog'`` reloader is much more efficient but requires
+        installing the ``watchdog`` package first.

+    :param request_handler: Use a different
+        :class:`~BaseHTTPServer.BaseHTTPRequestHandler` subclass to
+        handle requests.
+    :param static_files: A dict mapping URL prefixes to directories to
+        serve static files from using
+        :class:`~werkzeug.middleware.SharedDataMiddleware`.
+    :param passthrough_errors: Don't catch unhandled exceptions at the

+    :param ssl_context: Configure TLS to serve over HTTPS. Can be an
+        :class:`ssl.SSLContext` object, a ``(cert_file, key_file)``
+        tuple to create a typical context, or the string ``'adhoc'`` to

+            arguments.
+        -   a `str`:  The string is set as form data for the associated key.

+    URI with unquoted characters if it was not already quoted correctly,
+    but preserves the URL's semantics. Werkzeug uses this for the

+       is not portable.  It internally calls :meth:`readline`.
+
+       We strongly suggest using :meth:`read` only or using the

+       over a WSGI input stream.
