CACHE::disable iRule doesn't seem to be working.

Hi guys 

I need help ! 

 

Our customer wants to disable caching for GET requests, but the CACHE::disable iRule doesn't seem to be working. Do you have any suggestions?

 

thank you

  • thanks for your information 

    but below irule does not work,, f5 device can not send traffic to server after applied below irule

    idk the reason

     

    when HTTP_REQUEST priority 500 {

         if { [HTTP::header exist "Content-Type"] }  {
            if { [HTTP::header exist "Cookie"]  } { 
                CACHE::disable
                }
            CACHE::enable
            }        
    }

    when HTTP_RESPONSE priority 600 {

       if { [HTTP::status] == 200 }{
               if { [HTTP::header exist "Cookie"] } { 
                CACHE::disable
          }
          CACHE::enable
        }
    }

     

  • Hi neeeewbie

    I think this iRule will do.

    when HTTP_REQUEST priority 500 {
        if { [HTTP::method] equals "GET" } {
            CACHE::disable
        } else {
            CACHE::enable
        }
    }
