Hello!

Thanks for the comments.
Let me look into the Cookie and Vary answers in a later mail.

Below, is my reply about the proxy_pass question.

Yes, I tried this, but then app behind the proxy_pass gets a request like:

/not_logged_in_user/search?keyword=nginx

Which it fails on, because it does not recognize /not_logged_in_user/ or
/logged_in_user/ as part of its' path. Of course I could change the
backend app to recognize these paths, but that would be more wasted cpu
than having nginx do it.

Or am I missing something?

Thanks,
Zev
