Switch between OCSP Responder

Hi!

It's possible, using an iRule to switch between 2 different OCSP Responders. I've got an application that accepts two different client certificates for user authentication, here is the idea.

 
 if {$issuer_dn contains "OU=fnmt" }{ 
      FNMT Cert 
      Use Reponder 1 
 } elseif {$issuer_dn contains ",OU=dnie" }{ 
      DNIe Cert 
      Use Reponder 2 
 } else { 
      No valid cert 
 } 
 

Any suggestion? Thanks!
