<h1 class="topictitle1">Set up output compression for HTTP Server (powered by Apache)</h1>
<div><p>This topic provides information about how to set up output compression
for HTTP Server (powered by Apache) 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 output compression, a filter must be inserted in the
output filter chain. This is done using the SetOutputFilter directive. See <a href="rzaiecompression.htm">File compression for HTTP Server (powered by Apache)</a> for more information.</p>
<p>To set up output compression, 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">Output Filters</span> tab.</li>
<li>Add an output filter:<p>There are two types of output filters. The first
output filter type only requires a file extension and a filter name. The second
output filter type requires a MIME type and filter name. For both output filter
types, click <span class="uicontrol">Add</span> under the appropriate table and specify
the file extension, MIME type, and filter name.</p>
</li>
<li>Click <span class="uicontrol">Continue</span>.</li>
<li>Click <span class="uicontrol">Add</span> under the <strong>Set output filter</strong> table.</li>
<li>Specify DEFLATE for the filter name.</li>
<li>Click <span class="uicontrol">Apply</span>.</li>
</ol>
<p>You should now have something like the below example in your configuration.</p>
<dl><dt class="dlterm">Example</dt>
<dd><pre>AddOutputFilterByType DEFLATE text/html
AddOutputFilter DEFLATE .html
SetOutputFilter DEFLATE</pre>
</dd>
</dl>
