New to iRules use, help for client browser cache eliminaiton

Would like to append server response with " " in HTTP of specific pages.

"" "" eliminate all 's

If you want to insert into HTML then you have to collect the response (which is relatively CPU intensive), insert the header and then forward, however there is a much easier way to acheive the same thing using HTTP/1.1 Cache-Control headers;-

when HTTP_RESPONSE {
        if {[HTTP::header Content-Type] contains "html"} {
    HTTP::header insert Pragma "no-cache"
    HTTP::header insert Expires "Fri, 01 Jan 1990 00:00:00 GMT"
    HTTP::header replace Cache-Control "no-cache,no-store"
}
}
