| Sorry for top-quoting, but stuck with Outlook and fixed settings here at the office.
| Anyway, I found out that the web server does not use a Vary-header, so that wasn't the problem. After doing some manual tests and being unable the replicate the problem, I started to look harder at the two dumps below. Then it became pretty obvious.
| It seems that Explorer and Firefox requests urls in a different way.
| Explorer: /erez4/cache/online_master_arkiv_webbilleder_DIA_
| Firefox: /erez4/cache/online%5Fmaster%5Farkiv%5Fwebbilleder%5FDIA
| Of course that means diffent objects in the cache since varnish hashes on req.url. Is there a know workaround to this problem?

you could regsub it or with 3.0 I'd suggest having a vmod that just
normalises URLs and removes extra % escapes.
