Re: ssl_crtd breaks after short time

Hi,

James Lay just replied to me with his current config.. (pretty much like what he posted), and it seems he does not even try to use http_access rules to filter on urls from https requests..

@Amos: are you certain that there's not an error in how http_access rules are applied to bumped connections?

What I noted was:

Instead of having:
http_access allow CONNECT bumpedPorts

he has:
http_access allow SSL_ports

which somehow seems to work instead.

He only uses http_access allow rules for http sites.. he filters https on domain only - using:
acl allowed_https_sites ssl::server_name_regex "/opt/etc/squid/http_url.txt"
ssl_bump bump allowed_https_sites
ssl_bump terminate !allowed_https_sites

in my access log - using james lay's format - squid only logs CONNECT.. so it seems its not registering the step AFTER CONNECT as something seperate - which would explain why its not applying http_access filtering to it ?

I'm hoping someone can tell me what I've done wrong in my config.. I'm
obviously not understanding how it works when https is envolved.. it
works as intended with http..

It should be working. I'm a bit confused myself now why that CONNECT
line would be matching the decrypted requests, they definitely should
not be having the CONNECT request method as they are destined to an
origin server.

We've missed something basic, and will probably kick ourselves at how
simple when its reavealed. :-(
  All I can think of now is that James log format should be indicating
more clearly whats going on than the default Squid one will.
