Hi all, I'm posting for an ssl/acl problem.
In my configuration I have 2 proxies, 1 Internal proxy (used by internal users)
that serves internal websites and that escalate (cache_peer) to another proxy
(external) when needs to go outside.
My problem is that an internal server now needs to reach an external website
(via SSL/HTTPS) but I need to filter the access on just some paths (the
internal server will contact the internal squid that should user the cache_peer
to reach the "external" site).

http_port host11.domain.com:9999 ssl-bump generate-host-certificates=on
dynamic_cert_mem_cache_size=8MB cert=/path..../squid-CA.pem

After some tests I realized that ssl_bump works only when squid does direct
connect to websites but doesn't work when used with cache_peers, is it right ?
What would be to best way to achieve my scope ? Should I configure ssl_bump on
the external squid (I would prefer do it on the internal one to keep the
outside squid config the simplier possible) ? Actually to use the "url_regex"
acl to filter the path of an HTTPS site I have opened to also the CONNECT
method to the whole site ... Is this the right method to filter paths on an
https website?
Kind regards,
