<p>nghttp2 offers some high level Python API to C library. The bindings
currently provide HPACK compressor and decompressor classes and HTTP/2
server class.</p>
<p>The extension module is called <tt class="docutils literal"><span class="pre">nghttp2</span></tt>.</p>
<p><tt class="docutils literal"><span class="pre">make</span></tt> will build the bindings. The target Python version is
determined by configure script. If the detected Python version is not
what you expect, specify a path to Python executable in <tt class="docutils literal"><span class="pre">PYTHON</span></tt>
variable as an argument to configure script (e.g., <tt class="docutils literal"><span class="pre">./configure</span>
<span class="pre">PYTHON=/usr/bin/python3.4</span></tt>).</p>

because the deflater and inflater share the same amount of header
table and the inflater decides that number. The deflater may not
want to use all header table size because of limited memory
availability. In that case, <em>hd_table_bufsize_max</em> can be used to
cap the upper limit of table size whatever the header table size is
chosen by the inflater.</p>
