[squid-users] Sonicwall and empty url

Hello,
      I am new to Squid and I'd like to use it as a simple cache proxy
server for web browsing.

We use a Sonicwall appliance for firewalling, and we'd like to use the
"Proxy Web Server" option of Sonicwall.

This option performs automatic proxy forwarding of all web requests
coming from the lan (internal) interface of the Sonicwall. Users in the
lan will use proxy without configuring their browser, because the
Sonicwall automatically forwards packets to the proxy.

The Squid proxy is currently located on the DMZ, but can be located
anywhere outside the lan.

Now the problem:

Defining the Squid proxy in the "Proxy Web Server" field of the
Sonicwall, Squid always returns "Invalid URL", because receives an
empty URL.

If I use the same proxy from a browser, it works correctly.

Here there is an extract of the Squid Log:

http://www.cisco.com/ - DIRECT/198.133.219.25 text/html

As you can see, the requests from 212.131.168.53 (the browser) are
performed correctly, while requests from 10.192.45.54 (the redirection
from the Sonicwall) are empty.

I know (and tried) that the Sonicwall works with other proxies too
(i.e. Apache), so I don't understand what the problem is.

Any help?

Sincerely,

Vito Parisi
