[users@httpd] apache-2.0.42, mod_proxy and mod_cache issues

[Veselin Terzic <ve...@systems.dhl.com>]

non-ascii file namesdear apache users,

platform: linux red hat 7.2, apache 2.0.42 with mod_proxy and mod_cache

i use apache as a reverse proxy, i.e. using ProxyPass and ProxyPassReverse
to "accelerate" dozens of backend/web servers and different URLs.

scenario:

         (1)                             (2)
(3)                                             (4)
client----(internet)-->
SSL_termination_device--->apache-2.0.42_proxy_cache---->backend web servers

i have to maintain session persistency and i use "secure" cookies to achieve
that, but somehow sessions will get mixed up.
what is  exactly happening in the proxy engine and what is being cached that
can mix cookies up?

What is going to happen with HTTP/HTTPS traffic in the scenario above as it
pertains to RFC-2109 section 10.2 ?
Will mod_proxy pass cookie sent from the client to the server if the cookie
is "secure" and SSL is used only from the client to the SSL termination
engine (1-->2), but not from apache to the backend server?

Is apache-2.0.42 fully compliant with rfc-2616 and 2109?

Any help is greatly appreciated,
thanks
