Re: [squid-users] Squid 2.7.STABLE5 hangs with "HEAD" request in LOG

Hey Thomas,

The main issue is that the file "request" is kind of "stuck".
We need first to verify the issue which is not even clear enough.

Squid 2.7 OK then.
An update is preferred for comfort reasons but assuming there is another
issue for now.
Squid 2.7 is not in the support life time but I will try to eliminate
couple aspects about the issue.
Leaving firefox or explorer is smart.
Squid operates at the network level which is not even related to the
browser in the manner of "networking".
The browser uses squid to "get" content.
In a case you have a specific web site or specific issue try couple things:
Open firefox "private windows" which will use clean surfing no local
caching and other stuff.
Also remove any addons that runs on the browser.
Once it's up open the profiling and inspection interface in FF using:
Tools > Web Developer > Profiler.
it can also be shown with shift+f5
There you have a network tab which shows every detail about the page and
related content load.
enter a web site name and see what happens.
You should see how long it take between each request to load.
This level will show couple basic levels that can be understood fast.

I do not know what the network design and looks is so I would not even
assume couple things about the network infrastructure.
Since it's SLES11 I assume this node has 1Gbps network connection but
still Unsure.

The reasons for what you see can be couple and to make sure one step at
a time you will need to download this file using a simple software like
"wget" for example.
vwget(VisualWget) was built for windows.

The issue possibly not related directly to squid.
In this case that IE and Firefox do not load the content on the same
machine while using the same proxy and it reproducible it's something
that we can say "this" and then and only then we can see that squid 2.7
probably is OK while using only http\1.0.

The access log for example will write and show the log line after the
client received, from squid point of view, the whole response.
You can try to profile the site and see what happens to make sure that
there is or there isn't any issue.

Can you share the client machine hardware and software specs?
Can you share the server machine hardware specs?
