Try next irule (or different virtual server) if 404 response

Isn't it funny how sometimes when you post a question you immediately think of the answer? :)

 

 

For future ref for anyone who might need it...

 

 

Within HTTP_RESPONSE:

 

if { $partition eq "prod" && ([HTTP::status] eq "404") } {

 

if { $debug>=3 } { log local0.info "$castoruri not found in $partition castor domain. Falling back to legacy irule" }

 

set trylegacy 1

 

HTTP::retry $request

 

}

 

 

 

within HTTP_REQUEST:

 

if { [info exists trylegacy] && $trylegacy == 1 } {

 

if { $debug>=3 } { log local0.info "LEGACY REQUEST INITIALISED for $castoruri in $partition castor domain" }

 

virtual legacyvirtual

 

return

 

}
