Problems encouraging caching on the browser

We are a web-hosting site and we have an iRule setup to encourage caching on the client browsers. However, a lot of URIs that meet the iRule arguments are not being cached by clients running IE6.0. ...

We are still having trouble removing the Vary header via an iRule. I tried deleting it and then reinserting just what I want:

 

 

Vary: User-Agent

 

 

However, it doesn't seem to want to alter the header. In the meantime, we have removed compression, which in turn, removes the Vary header and the files are now being cached in IE.

 

 

Please let us know if there is any other specific syntac I can use in my iRule to kill the Vary header from these large files. Thanks!

 

 

 

The LTM is inserting the Vary header after the iRule processes the server response. This is why you don't see a change in the Vary header. I'm working on a slightly similar case, but will post here once I find a solution that makes sense for you to use.
