Re: [squid-users] Passing a URL directly to squid through the web browser...

Hello,
I gess you need somehow to get to your personal proxy because the
company proxy blocks URL you want to go to.

Even a very resctrictive WWW proxy usually allows the CONNECT method,
which a need for HTTPS to work. If you can access an HTTPS URL, it means
your proxy allows CONNECT (or HTTPS port 443 is not blocked by your
company firewall).

I usually use the CONNECT method and an SSH tunnel to get to the net
through a resctrictive company proxy.
So I open an SSH connection to my Linux server where I have my http
proxy (e.g. tinyproxy for Linux is sufficient for this) and within this
SSH connection I redirect a local port (the box I'm working at at work)
to this proxy, e.g. localhost:3128 -> myserver:3128

Then you just configure your Web-browser to use localhost:3128 as an
http-proxy and that is it. Your http traffic goes throgh the ssh tunnel
to your remote proxy.

Unfortunately, I am not sitting behind a proxy at the moment so I don't
have more details to share.

I just googled and I believe this is what I used a year ago:
http://bama.ua.edu/cgi-bin/man-cgi?ssh-http-proxy-connect+1
Putty (ssh client for Win) also support HTTP proxy and connect.

Some restrictive company proxies let you make a CONNECT to the 443 port
only (port dedicated for HTTPS). In such a case you need to modify the
ssh daemon at your remote box you want to connect to so it listen at
port 443.

There is also another possibility - an HTTP tunnel solution.
Search google for "HTTP tunnel".

Marji
