Content Adaptation for HTTP Requests with Symantec

Is it possible to check ICAP response. Either replace icap response 201 with 204 or send request header 204 in icap request. Also if possible icap response comes with 201 icap status then session will be drop by F5 before forwarding to webserver and user notification will be sent.

I tried below iRule but not worked.

            when ICAP_RESPONSE { 
           if { [ICAP::status] contains "201" } {  
                   [ICAP::status] replace 204
                          pool pool_testing
                }
            }
OR
            when ICAP_RESPONSE { 
                 if { [ICAP::status] contains "201" } {  
              set [ICAP::status] 204
               pool pool_testing
                 }
            }
