Hi,     I am looking for an iRule to exclude certain content type from being ram cached thus going beyond the uri exclusion list...     Any help would be appreciated.       Jon ...

Hi Jon,

You'll need to do something like this: 

 
class bypass_ram_cache_filetypes {
   {
      "mp3"
      "pdf"
      "wmv"
   }
}

rule bypass_ram_cache_by_filetype {
   when HTTP_REQUEST {
        if { [class match [HTTP::path] ends_with $::bypass_ram_cache_filetypes] } {
                log local0. "RAM Cache bypassed for [HTTP::path]"
                CACHE::disable
        }
}
}
