Should be working, so I think something else is the issue. Here's some
things to consider off the top of my head. If none of them help, maybe
post your vcl_recv() function, anonymized if necessary.
- Are you sure your second attempt was fetched from the origin, and
not a cached result from earlier attempts?
- If you have any conditional logic in vcl_recv double-check you're
not returning before you overwrite the host header or something
along those lines.
- Double-check you're sending a host header it'll understand, e.g.
including or excluding the "www." in front as required.
- Is Varnish using the correct backend for that host?
- It might be worth watching the log output and seeing what headers
Varnish is sending in the request to the backend; and/or you could
modify your backend so the default page for unrecognised hosts is a
script that outputs the value of the host header it received, and
maybe also the date+time the response was generated.
