no-cache Irule

We are wanting to force caching and set the maxage via an irule except on a certain link. We tried this rule but it doesnt seem to work ALL the time. Thoughts?

 

 

when HTTP_REQUEST {

 

DEFAULT cache value for all pages

 

set cache_value "public, max-age=300"

 

 

 

center should not be cached

 

if { [HTTP::uri] contains "/center" } {

 

set cache_value "private, no-cache"

 

}

 

}

 

when HTTP_RESPONSE {

 

HTTP::header replace Cache-control $cache_value

 

}

    Hi Jason,

     

     

    That iRule looks fine. When you say it doesn't work all of the time what do you mean? Are you seeing some responses without the Cache-Control header set? If so, do you have fast cache or Web Accelerator enabled on the virtual server?

    what happens is we see the "private" insert coming through most of the time but we also see a S-Cache tag through as well... which is strange.
