<h1 class="topictitle1">Set up input decompression for HTTP Server (powered by Apache)</h1>
<div><p>This topic provides information about how to set up input decompression
for GZIP compressed input bodies for HTTP Server with the <span>IBM<sup>®</sup> Web Administration for i5/OS™ interface</span>.</p>
<div class="important"><span class="importanttitle">Important:</span> Information
for this topic supports the latest PTF levels for HTTP Server for i5/OS .
It is recommended that you install the latest PTFs to upgrade to the latest
level of the HTTP Server for i5/OS. Some of the topics documented here are
not available prior to this update. See <a href="http://www-03.ibm.com/servers/eserver/iseries/software/http/services/service.html" target="_blank">http://www.ibm.com/servers/eserver/iseries/software/http/services/service.htm</a> <img src="www.gif" alt="Link outside Information Center" /> for more information. </div>
<p>In order to set up input decompression, a filter must be inserted in the
input filter chain. This is done using the SetInputFilter directive. WebDAV
makes frequent use of compression, and as such, input decompression is used
primarily with WebDAV. The range of usefulness of input decompression is also
determined by Web browser support. Most Web browsers do not support compressed
data or have limited support. Compressed information is only accessible with
Web browsers with HTTP/1.1 support. See <a href="rzaiecompression.htm">File compression for HTTP Server (powered by Apache)</a> for more information.</p>
<p>To set up input decompression, do the following:</p>
<ol><li>Click the <span class="uicontrol">Manage</span> tab.</li>
<li>Click the <span class="uicontrol">HTTP Servers</span> subtab.</li>
<li>Select your HTTP Server (powered by Apache) from the <span class="uicontrol">Server</span> list.</li>
<li>Select the <a href="rzaiecontext.htm">context</a> you
want to work with from the <span class="uicontrol">Server area</span> list.</li>
<li>Expand <span class="uicontrol">Server Properties</span>.</li>
<li>Click <span class="uicontrol">Compression</span>.</li>
<li>Click the <span class="uicontrol">Input Filter</span> tab.</li>
<li>Click <span class="uicontrol">Add</span> under the <strong>Set input filter</strong> table.</li>
<li>Specify DEFLATE for the filter name under the <strong>Filter name</strong> column.</li>
<li>Click <span class="uicontrol">Apply</span>.</li>
</ol>
<p>You should now have something like the below example in your configuration.</p>
