Documentation
=============

Testing
-------

* A fixture for testing WSGI applications conveniently and in-process,
  in ``paste.fixture``

* A fixture for testing command-line applications, also in
  ``paste.fixture``

* Check components for WSGI-compliance in ``paste.lint``

* Check filesystem changes, with ``paste.debug.fsdiff``

Server
------

* A threaded HTTP server in ``paste.httpserver``

* A tool for seeing and killing errant threads in the HTTP server, in
  ``paste.debug.watchthreads``

Dispatching
-----------

* Chain and cascade WSGI applications (returning the first non-error
  response) in ``paste.cascade``

* Dispatch to several WSGI applications based on URL prefixes, in
  ``paste.urlmap``

* Allow applications to make subrequests and forward requests
  internally, in ``paste.recursive``

* Redirect error pages (e.g., 404 Not Found) to custom error pages, in
  ``paste.errordocument``.

Web Application
---------------

* Easily deal with incoming requests and sending a response in
  ``paste.wsgiwrappers``

* Work directly with the WSGI environment in ``paste.request``

* Run CGI programs as WSGI applications in ``paste.cgiapp``

* Traverse files and load WSGI applications from ``.py`` files (or
  static files), in ``paste.urlparser``

* Serve static directories of files, also in ``paste.urlparser``; also
  serve using the Setuptools ``pkg_resources`` resource API.

* Proxy to other servers, treating external HTTP servers as WSGI
  applications, in ``paste.proxy``.

* Serve files (with support for ``If-Modified-Since``, etc) in
  ``paste.fileapp``

Tools
-----

* Catch HTTP-related exceptions (e.g., ``HTTPNotFound``) and turn them
  into proper responses in ``paste.httpexceptions``

* Manage HTTP header fields with ``paste.httpheaders``

* Handle authentication/identification of requests in ``paste.auth``

* Create sessions in ``paste.session`` and ``paste.flup_session``

* Gzip responses in ``paste.gzipper``

* A wide variety of routines for manipulating WSGI requests and
  producing responses, in ``paste.request``, ``paste.response`` and
  ``paste.wsgilib``.

* Create Apache-style logs in ``paste.translogger``

* Handy request and response wrappers in ``paste.wsgiwrappers``

* Handling of request-local module globals sanely in ``paste.registry``

Authentication
--------------

* Authentication using cookies in ``paste.auth.cookie`` and
  ``paste.auth.auth_tkt``; login form in ``paste.auth.form``

* Authentication using `OpenID <http://openid.net/>`_ in
  ``paste.auth.open_id``, using `CAS
  <http://www.ja-sig.org/products/cas/>`_ in ``paste.auth.cas``

* HTTP authentication in ``paste.auth.basic`` and
  ``paste.auth.digest``

* Dispatch to different authentication methods based on User-Agent, in
  ``paste.auth.multi``

* Grant roles based on IP addresses, in ``paste.auth.grantip``

Debugging Filters
-----------------

* Catch (optionally email) errors with extended tracebacks (using
  Zope/ZPT conventions) in ``paste.exceptions``

* During debugging, show tracebacks with information about each stack
  frame, including an interactive prompt that runs in the individual
  stack frames, in ``paste.evalexception``.

* Catch errors presenting a `cgitb
  <http://python.org/doc/current/lib/module-cgitb.html>`_-based
  output, in ``paste.cgitb_catcher``.

* Profile each request and append profiling information to the HTML,
  in ``paste.debug.profile``

* Capture ``print`` output and present it in the browser for
  debugging, in ``paste.debug.prints``

* Validate all HTML output from applications using the `WDG Validator
  <http://www.htmlhelp.com/tools/validator/>`_, appending any errors
  or warnings to the page, in ``paste.debug.wdg_validator``

Other Tools
-----------

* A file monitor to allow restarting the server when files have been
  updated (for automatic restarting when editing code) in
  ``paste.reloader``

* A class for generating and traversing URLs, and creating associated
  HTML code, in ``paste.url``

* A small templating language (for internal use) in
  ``paste.util.template``

* A class to help with loops in templates, in ``paste.util.looper``

* Import modules and objects given a string, in
  ``paste.util.import_string``

* Ordered dictionary that can have multiple values with the same key,
  in ``paste.util.multidict``
