11.6.1 HTTPConnection Objects
</H2>

<P>
<tt class="class">HTTPConnection</tt> instances have the following methods:

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3316' xml:id='l2h-3316' class="method">request</tt></b>(</nobr></td>
  <td><var>method, url</var><big>[</big><var>, body</var><big>[</big><var>, headers</var><big>]</big><var></var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
This will send a request to the server using the HTTP request method
<var>method</var> and the selector <var>url</var>.  If the <var>body</var> argument is
present, it should be a string of data to send after the headers are finished.
The header Content-Length is automatically set to the correct value.
The <var>headers</var> argument should be a mapping of extra HTTP headers to send
with the request.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3317' xml:id='l2h-3317' class="method">getresponse</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
Should be called after a request is sent to get the response from the server.
Returns an <tt class="class">HTTPResponse</tt> instance.
<span class="note"><b class="label">Note:</b>
Note that you must have read the whole response before you can send a new
request to the server.</span>
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3318' xml:id='l2h-3318' class="method">set_debuglevel</tt></b>(</nobr></td>
  <td><var>level</var>)</td></tr></table></dt>
<dd>
Set the debugging level (the amount of debugging output printed).
The default debug level is <code>0</code>, meaning no debugging output is
printed.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3319' xml:id='l2h-3319' class="method">connect</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
Connect to the server specified when the object was created.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3320' xml:id='l2h-3320' class="method">close</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
Close the connection to the server.
</dl>

<P>
As an alternative to using the <tt class="method">request()</tt> method described above,
you can also send your request step by step, by using the four functions
below.

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3321' xml:id='l2h-3321' class="method">putrequest</tt></b>(</nobr></td>
  <td><var>request, selector</var><big>[</big><var>,
skip_host</var><big>[</big><var>, skip_accept_encoding</var><big>]</big><var></var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
This should be the first call after the connection to the server has
been made.  It sends a line to the server consisting of the
<var>request</var> string, the <var>selector</var> string, and the HTTP version
(<code>HTTP/1.1</code>).  To disable automatic sending of <code>Host:</code> or
<code>Accept-Encoding:</code> headers (for example to accept additional
content encodings), specify <var>skip_host</var> or <var>skip_accept_encoding</var>
with non-False values.

<span class="versionnote">Changed in version 2.4:
<var>skip_accept_encoding</var> argument added.</span>

</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3322' xml:id='l2h-3322' class="method">putheader</tt></b>(</nobr></td>
  <td><var>header, argument</var><big>[</big><var>, ...</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
Send an <a class="rfc" id='rfcref-90106' xml:id='rfcref-90106'
href="http://www.faqs.org/rfcs/rfc822.html">RFC 822</a>-style header to the server.  It sends a line to the
server consisting of the header, a colon and a space, and the first
argument.  If more arguments are given, continuation lines are sent,
each consisting of a tab and an argument.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3323' xml:id='l2h-3323' class="method">endheaders</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
Send a blank line to the server, signalling the end of the headers.
</dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-3324' xml:id='l2h-3324' class="method">send</tt></b>(</nobr></td>
  <td><var>data</var>)</td></tr></table></dt>
<dd>
Send data to the server.  This should be used directly only after the
<tt class="method">endheaders()</tt> method has been called and before
<tt class="method">getresponse()</tt> is called.
</dl>
