Are iRule instances scoped to a request/response?

Hmmm, thanks for that info. I am now worried about my iRule.

The iRule is looking for a particular request parameter in the request, and (if found) capturing it in the cnParamValue variable. In the response handling of the iRule I set a cookie using that cnParamValue.

My hope was to set this cookie for the initial request of a resource; all subsequent requests for the duration of that browser session would include the cookie. This include requests for html, css, js, ajax calls, etc.

Is this going to work? Browsers can create multiple connections to fetch resources. Will each of those connections receive the cookie value sent from that one initial request?

If not, is there an alternate approach to this problem?

Thanks!
