Hi Vitaly,
It would probably be easier to help if you posted a log dump of the same url in two browsers.

Hello,
So I am still trying to figure out why I cant hit a cached page with a different browser other then the one it was cached with. I am pretty sure i got my vary statements right, they show up similar in the logs, so I know I am missing something.
Can there be something other then Vary tags that can be causing this?
Thank you.
