I tried it with Mozilla Firefox 3.6.13 by writing 192.168.1.10 port
3128 to the Prefereces > Network > Configuration. Configured Internet
Explorer by Tools > Internet Options > Connections > Local Network
Configuration and typing proxy IP and PORT. Google Chrome acquires the
options from system so it is the same as IE.

Client is windows configured to use a static IP 192.168.1.120 with
255.255.255.0 subnet mask and 192.168.1.1 gateway (and dns). Hosts
equivalent is name address mapping I assume, which I found nothing
about (except 127.0.0.1 <-> localhost I guess)

I sometimes think that the javascript makes an explicit request which
leads to that misinterpretation by the browsers. I have no strong
clues about though. And I also want to ask if we can make some
workaroud from proxy layer without involving browsers. As I previously
said: Can Squid Proxy fix such bad requests by concaneting other
fields from HTTP request to build the correct URL?
