Hi. I'm testing out Varnish 4.0 finally. I'm super excited about the IMS stuff and am dying to use it. And a big congratulations on the 4.0 release.
I was playing with porting our shared hosting configuration to 4.0 and ran into a slight weirdness with IMS. Keeping in mind that we do a number of things to make things play nicely with the fact that we have no idea what our customers might be doing (and therefore have to jump through a bunch of crazy hoops to make sure we don't return things like authenticated content to unauthenticated users), this could very easily be something weird with our particular setup. I've re-run the test a bunch of times and seen the same thing each time. Here's the scenario: * I have IMS up and running and working. Other than this one particular oddity, everything else IMS-related seems to be working great and I'm greatly looking forward to using it. The test page I'm using deliberately returns a TTL of 1 second to make testing easier. * As a mockup of a customer doing something like cookie-base authentication, or IP-based .htaccess authentication, I wrote up a simple rewrite rule to return a 403 if a certain cookie was missing. * I turn off the rewrite rule * Do a request to that page a few times with the expected 200 from the backend. On the 2nd and subsequent reqs, the IMS stuff kicks in. BTW, is the client getting a "HTTP/1.1 200 Not Modified" the expected behavior? I know the strings after the status code are completely arbitrary but it looked a bit odd. * I turn the rewrite rule back *on* * Do the request again. Here's where it gets odd. * Varnish does an IMS request to the backend * The backend responds with a 403 as expected. * Varnish replies to the client with a HTTP/1.1 200 Not Modified I would expect an error status (or really anything that's not a 304) to fail the IMS test on Varnish's side and that it would then return the 403 to the client. Something weird about what I'm doing/abusing?
