I am currently trying to create an ACL based on the value of the Set-Cookie Header of an HTTP Response given by one of the backend servers. Based on this, being the response an HTTP 301 Moved Permanently, I need to change the Location to which the browser will be then redirected.
This is how it looks right now:
However, I am getting the following error:
“acl ‘is_new_bck’ will never match because it only involves keywords that are incompatible with 'frontend http-response header rule”
Can someone help me with this? Where should I put this check? The rspirep works fine. What I need is how to configure the ACL rule.
