ICAP with iRule Response Page without ASM

Thanks Niels for your response. I tried this Irule but got the Connection timeout error. I created below Irule and it's working as expected-

when HTTP_REQUEST {

set VirusDetected 0

log local0. "AOB-TEST iRule initiated and VirusDetected variable to 0"

}

when ADAPT_REQUEST_RESULT {

       if { ([ADAPT::result request] contains "respond") } {

           set VirusDetected 1

           log local0. "ICAP: Check ADAPT VAR: == $VirusDetected => Virus Found"

           }

        else {

           set ADAPTvar 0

           log local0. "ICAP: Check ADAPT VAR: == $VirusDetected=> Virus NOT Found"

       }

   }

when HTTP_RESPONSE_RELEASE {

if { $VirusDetected == 1 } {

 HTTP::respond 301 Location "https://xxxxx.xxxx.com/virustest"

 log local0. "redirected to corporate network after Virus was Dectected"

   }

}
