Thanks for the clarification and I agree with you
completely. a multipath and a round-robin DNS method will return different records between our DNS calculation and the final squid results It is true that it would be possible to use an external_acl in the http_reply_access. Do you think that adding it in this position I would be able to use squid's resolution results ? Le 16/09/2021 à 19:43, Alex Rousskov a

There have been many complaints about associated problems from folks that went this route... I am not sure what you are trying to do with that a %<a-based external ACL in Squid, so it is difficult to narrow down the solution search scope, but Squid does support slow ACLs in certain directives used when talking to origin servers or peers (after built-in DNS resolution and destination selection) so perhaps there is a way to do what you want without Squid modifications. If there is not, it would not be difficult to add a post-resolution directive that supports slow ACLs IMO, but, again, that requires more knowledge of the use case -- there are several places where such a directive can be added.

This makes me plan having to develop a function that has to perform DNS resolution inside the helper with the performance consequences that this will impose.I would be looking at a design where a helper classifies requests and using that later on when the server is known to match up the IP vs the classification. I'm struggling to think of a flow that works efficiently though.
