Hi, Okay – but what happens if you are communicating with a non REST endpoint. Consider a Web services endpoint for example where a request is only interacted with via POST but the operation for example may frequently be a read based function akin to a HTTP GET? Is Squid just simply not going to help cache those requests? It is only helpful for more strict alignment to REST principles?

It can only extend or shrink cacheability times.
