Sectively compression for url using “*.uif”.

Hi Neo,

I think you'll want to enable/disable compression in HTTP_RESPONSE based on the response content-type. Though I'm not sure it makes sense to try to compress all content from the pool that's not already compressed. I think you'd want to try to limit compression to content-types which can be compressed like text.

Also, do you want to enable or disable response compression for *.uif file requests? It looks like UIF files might already be compressed ISO images.

As far as the HTTP profile setting, the COMPRESS::enable wiki page states the following:

http://devcentral.f5.com/wiki/default.aspx/iRules/COMPRESS__enable.html

Note that when using this command, you must set the HTTP profile setting Compression to Selective.

when HTTP_REQUEST {

    Prevent response compression if request is for a uif filetype
   switch -glob [HTTP::path] {
      "*.uif" {
         set compress 0
      }
      default {
 set compress 1
      }
   }
}
when HTTP_RESPONSE {

    Enable compression if request was not for a uif filetype,
    the response isn't already compressed and
    the response is text-based
   if {$compress and [HTTP::header Content-Encoding] ne "gzip" and [HTTP::header Content-Type] contains "text"}{
       COMPRESS::enable
   }
}
