Hi Everyone,
I am trying to run Squid in my network on a Windows XP machine.
Everything is fine when working from localhost; on other localnet
machines I cant make a search on google because I consistently get
Invalid Request reply from it when I type the search phrase and hit
enter. I added:
acl our_networks src 192.168.1.0/24 192.168.2.0/24
http_access allow our_networks
http_access allow localhost
to the default configuration shipped with the package.
When I sniffed the packets I saw nothing weirdly different between
two
scenarios (localhost/localnet). The localhost request:
--------
GET http://www.google.com/ HTTP/1.1

application/x-shockwave-flash, application/vnd.ms-excel,

and this works fine. The localnet counterpart:
-------
GET

HTTP/1.1
Note the missing http://domain details in the URL. This is not a
browser->proxy HTTP request. It is a browsers->origin request.
IIRC interception of this type of request does not work in Windows,
since the kernel NAT details are not available without proprietary
third-party network drivers. Look at WPAD configuration of the localnet
browsers instead, that way they will send browser->proxy requests
nicely.
