  <h2>Httplib2</h2>
  <p>A comprehensive HTTP client library, <code>httplib2.py</code>
  supports many features left out of other HTTP libraries.
  </p>
  <dl>
  <dt>HTTP and HTTPS</dt>
  <dd>HTTPS support is only available if the socket module was compiled with SSL support.
  </dd>

  <dt>Keep-Alive</dt>
  <dd>Supports HTTP 1.1 Keep-Alive, keeping the socket
  open and performing multiple requests over the same connection
  if possible.
  </dd>

  <dt>Authentication</dt>
  <dd>The following types of HTTP Authentication are supported.
  These can be used over both HTTP and HTTPS.
  <ul>
  <li><a href="http://www.faqs.org/rfcs/rfc2617.html">Digest</a></li>
  <li><a href="http://www.faqs.org/rfcs/rfc2617.html">Basic</a></li>
  <li><a href="http://www.xml.com/pub/a/2003/12/17/dive.html">WSSE</a></li>
  <li><a href="http://franklinmint.fm/2006/02/28/draft-sayre-http-hmac-digest.html">HMAC Digest</a></li>
  <li><a href="http://code.google.com/apis/accounts/AuthForInstalledApps.html">Google Account Authentication</a></li>
  </ul>
  </dd>

  <dt>Caching</dt>
  <dd>The module can optionally operate with a private
  cache that understands the Cache-Control: header and
  uses both the ETag and Last-Modified cache validators.
  </dd>

  <dt>All Methods</dt>
  <dd>The module can handle any HTTP request method, not just GET and POST.</dd>

  <dt>Redirects</dt>
  <dd>Automatically follows 3XX redirects on GETs.</dd>

  <dt>Compression</dt>
  <dd>Handles both 'deflate' and 'gzip' types of compression.</dd>

  <dt>Lost update support</dt>
  <dd>Automatically adds back ETags into PUT requests to resources
  we have already cached. This implements Section 3.2 of
  <a href="http://www.w3.org/1999/04/Editing/#Table">Detecting the Lost Update Problem Using Unreserved Checkout</a></dd>

  <dt>Unit Tested</dt>
  <dd>A large and growing set of unit tests.</dd>

  </dl>

 <h3>Usage</h3>

 <p>A simple retrieval:</p>

 <pre><code>import httplib2
 h = httplib2.Http(".cache")
 resp, content = h.request("http://example.org/", "GET")
 </code></pre>

 <p>The 'content' is the content retrieved from the URL.
 The content is already decompressed or unzipped if necessary.
 The 'resp' contains all the response headers.
 </p>

 <p>To PUT some content to a server that uses SSL
 and Basic authentication:</p>

 <pre><code>import httplib2
 h = httplib2.Http(".cache")
 h.add_credentials('name', 'password')
 resp, content = h.request("https://example.org/chap/2",
  "PUT", body="This is text",
  headers={'content-type':'text/plain'} )
 </code></pre>

 <p>Use the Cache-Control: header to control
  how the caching operates.</p>

 <pre><code>import httplib2
 h = httplib2.Http(".cache")
 resp, content = h.request("http://bitworking.org/")
  ...
 resp, content = h.request("http://bitworking.org/",
  headers={'cache-control':'no-cache'})
 </code></pre>

 <p>The first request will be cached and since this is a request to
 bitworking.org it will be set to be cached for two hours, because
 that is how I have my server configured.
 Any subsequent GET to that URI will return the value from the
 on-disk cache and no request will be made to the server.
 You can use the Cache-Control: header to change the caches behavior and
 in this example the second request adds the Cache-Control: header with a value
 of 'no-cache' which tells the library that the cached copy
 must not be used when handling this request.
 </p>

 <h3>Requirements</h3>

 <p>Requires Python 2.7, 3.4, or later. Does not require
 any libraries beyond what is found in the core library.</p>

 <h3>Download/Installation</h3>

 <p>The latest release of httplib2 is 0.3.0 and
 can be <a href="dist">downloaded from the from
  the dist directory</a>. See the
 <a href="CHANGELOG">CHANGELOG</a> for what's new in this
 version.</p>


 <p>The httplib2 module is shipped as a distutils package. To install
 the library, first unpack the distribution archive, and issue the following
 command:</p>

 <pre><code>$ python setup.py install</code></pre>

 <p><a href="dist">Download the distribution archives from here</a>. </p>

 <p> <a href="test">The resources used in the unit test cases</a>
  are available also. More documentation on them will be forthcoming.</p>

 <p>You can also get the sources directly from the SourceForge hosted
  subversion repository.</p>

 <pre>svn co https://httplib2.svn.sourceforge.net/svnroot/httplib2/trunk httplib2</pre>


 <h3>Documentation</h3>

 <p>In addition to the <a href="ref/">Python library style documentation</a> there
 are also two articles on XML.com, <a href="http://www.xml.com/pub/a/2006/02/01/doing-http-caching-right-introducing-httplib2.html">
  Doing HTTP Caching Right: Introducing httplib2</a> and

 <h3>Feedback</h3>

 <p>Bugs and enhancement requests are handled through
 <a href="http://sourceforge.net/projects/httplib2/">SourceForge</a>, and anything is up for discussion
 on the <a href="http://sourceforge.net/mail/?group_id=161082">httplib2 mailing list</a>.
 </p>

 <h3>To Do</h3>

 <p>This module is not perfect and needs the following:</p>
 <ul>
  <li>Support for Proxies</li>
  <li>A pluggable store for the cache is in place, with plugins for
  flat files and memcached.
  I eventually want to have plugins that allow keeping the cache in Berkeley DB, MySQL, etc.</li>
  <li>More unit tests</li>
 </ul>

 <h3>Project Goal</h3>

 <p>To become a worthy addition to the Python core library.</p>
