Hello, I have a bit of an urgent issue - Squid is serving 400 errors, and I'd like to avoid that. Ideally, we want Squid to serve the object that it has in cache, instead of the 400. I have stale-if-error=1800 in the headers, but squid is still serving a 400 whenever it gets it from the origin (webserver). We don't want 400's served at all.
So, as the subject says, does a stale-if-error header apply to 400 status requests?
