Squid3 - New GUI with sync, normal and reverse proxy

ccesario

So I am using squid2.7 and squidguard here on work and posting many times on the forum and there is not that "bug". Perhaps some parameters on squid3 which causes this problems. Perhaps POST HEADER size or something like that.

Do you have an URL where we can "spam" posts to test this ? Probably it is not the best to do with pfsense forum ;o)

Hehehehh no, I don't have URL to can "spam" posts. But using pfsense forum its possible.

Edit your posts and save-it :) … I my tests I usage this to reproduce many times the error :)

Thanks

Will do this perhaps this afternoon/night when I am at home. Perhaps we can tweak something if it's not a bug. :-)

Maybe a compile option like 'Be strictly HTTP compliant'

Hmm, no luck till now.

tried with different browsers (IE8 and FF11)
tried with (re)moving some refresh_patterns
tried with different DNS servers for squid (8.8.8.8 and 127.0.0.1)
added this to custom options to get more information from access.log

strip_query_terms off

This is a difference I found on squid access.log

The 503 line uses DNS and the 302 uses an IP address…

If I click on the URL posted in the error page I get returned to the post edit page and got an error message from pfsense forum:


Your session timed out while posting. Please try to re-submit your message. No subject was filled in. The message body was left empty.

hmmm…

Marcello and others,

I've still got problems configuring Squid 3 as a reverse proxy. Somehow I can't manage it to work properly.
As you illustrated in the forst postings I did exactly the same and added NAT and Firewall rules. I'm using port 8080 and 8443.

How come…?!?!

Thanks a lot,
Canefield

Still the same issue from TMG post? Did you removed the Nat?

Another bugs found on system log when I use revers proxy.

Solved! I found this problem because at dansquardian has banned "extension files". After I disable banned at extension tab, the error has gone.

Donny,
Check if does not happen if you uncheck dynamic content options on squid cache tab.

i can't seem to get this package to cache files at all… no errors and whatismyip.com detects the proxy is working just it always downloads files without looking at the cache store... anyone else got this problem?

If you know how to handle squid.conf files, can you check if your squid.conf file is ok?

The cache info is there…

Can you grep for TCP_CACHE your squid access_log file?

Version 2.0.4 is out with

bug and typo fixes
Upstream tab is now remote cache to enable multiple peer/sibling cache config
New compilation to avoid refresh_pattern and transparent mode errors

Thanks for all feedback specially to ccesario.

I recommend a package uninstall/install instead of reinstall to be sure old squid3 binaries are removed.

att,
Marcello Coutinho
