How can I enable compression of the web pages served?
http://www.desknow.com/kb/idx/5/182/article/

It is possible to enable gzip compression of the web pages served by DeskNow. This can be useful to save bandwidth, but incurs in a small performance hit.

To enable compression, edit the \desknow\conf\server.xml file, locate the normal (non-SSL, typically on  port 80) "Connector" element, and add the following attribute:

compression="on"

Example:

<Connector port="80"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" debug="0" redirectPort="443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" compression="on"/>

We do not recommend enabling compression for SSL connections, as some browsers may have issues with it.
