<h3 class="section">3.7 Poor Man's Multiplexing</h3>
<p><a name="index-Poor-Man_0027s-Multiplexing-126"></a><a name="index-multiplexing-127"></a><a name="index-pmmSize-128"></a><a name="index-pmmFirstSize-129"></a>
By default, Polipo does not use Poor Man's Multiplexing (see <a href="Poor-Mans-Multiplexing.html#Poor-Mans-Multiplexing">Poor Mans Multiplexing</a>). If the variable <code>pmmSize</code> is set to a
positive value, Polipo will use PMM when speaking to servers that are
known to support pipelining. It will request resources by segments of
<code>pmmSize</code> bytes. The first segment requested has a size of
<code>pmmFirstSize</code>, which defaults to twice <code>pmmSize</code>.
<p>PMM is an intrinsically unreliable technique. Polipo makes heroic
efforts to make it at least usable, requesting that the server disable
PMM when not useful (by using the ‘<samp><span class="samp">If-Range</span></samp>’ header) and
disabling it on its own if a resource turns out to be dynamic.
Notwithstanding these precautions, unless the server
cooperates<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a>,
you will see failures when using PMM, which will usually result in
blank pages and broken image icons; hitting <em>Reload</em> on your
browser will usually cause Polipo to notice that something went wrong
and correct the problem.
