Re: flow:established still broken in 2.9.0.5?

Not sure.

Definitely make sure 3128 is in "ports both" in stream5 and in "ports"
for http_inspect. Both of these are set in the default config in the
2.9.1_beta. Also add CONNECT to http_methods since only GET and POST
are included by default.

I would *guess* that to ignore the ssl traffic 3128 would also have to
be in the ssl preprossor port list, but I don't know what affect that
would have on performance since both HTTP and HTTPS are using the same
port.

If you are frequently getting FP on ssl/tls/ssh traffic, even though

both the ssl/ssh preprocessors and in stream5.

How does that work for a proxy? i.e. port 3128 supports both HTTP (via
GET/POST/etc) and HTTPS (via CONNECT method - and indeed isn't
guaranteed to be SSL anyway)

Thanks
