iRule to allow HTTP Error code through ASM policy

Hello,

I have an ASM policy applied to a virtual server. The ASM policy is configured to block HTTP 500 response codes.

I would like to write an irule that would allow HTTP 500 to be returned to clients that are in a pre-defined Data group list.

when HTTP_RESPONSE

{

if { [HTTP::status] eq "500" }

{

if { [class match [IP::client_addr] equals DATA_GROUP_LIST] }

{

commands to allow HTTP 500 response

} 

}

I'm actually trying to figure out if this is even possible. or are response codes all-or-nothing when enforced via an ASM policy?

Any help would be greatly appreciated.

Thank you.

Chris
