iRule header removal for cached item reponses

I should've done more research before putting in this ask.

I found the CACHE_RESPONSE event and I can manipulate it just like the HTTP_RESPONSE event

when RULE_INIT {
set static::InfoHeaders { "Server" "X-Powered-By" "X-SharePointHealthScore" "X-AspNet-Version" "X-AspNetMvc-Version" }}

when HTTP_RESPONSE { 
 Remove headers that provide information about the backend
foreach header $static::InfoHeaders {
    HTTP::header remove $header
}

when CACHE_RESPONSE { 
 Remove headers that provide information about the backend
foreach header $static::InfoHeaders {
    CACHE::header remove $header
}}
