[squid-users] Incorrect HTTP GET request from squid

OK here's the deal. I have 5 brand new Sun Cobalt CacheRaq4's straight out of the box using the default configuration. When I was doing some testing before putting the boxes into production I was encountering some strange problems with certain websites. Prime example is http://www.smh.com.au. If I go to this site bypassing the cache server I get the proper site. If I configure my browser to go through the cache server I get http://www.f2.com.au returned to my browser. Now both of these sites have the same IP address returned from a DNS query. I put a sniffer on my network to capture traffic to/from the cache server to see what was happening and the following is an extract from these captures.
This is the packet from my browser to the cache server with the HTTP GET request

Ethernet II Internet Protocol, Src Addr: (192.168.21.111), Dst Addr: (10.65.9.132) Transmission Control Protocol, Src Port: 1112 (1112), Dst Port: 3128 (3128), Seq: 5 Hypertext Transfer Protocol GET http://www.smh.com.au/ HTTP/1.0\r\n Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms Accept-Language: en-au\r\n User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)\r\n Host: www.smh.com.au\r\n Proxy-Connection: Keep-Alive\r\n \r\n

This is the packet from the cache server to the www.smh.com.au server

Ethernet II Internet Protocol, Src Addr: (10.65.9.132), Dst Addr: (203.26.51.42) Transmission Control Protocol, Src Port: 3100 (3100), Dst Port: 80 (80), Seq: 30173 Hypertext Transfer Protocol GET / HTTP/1.0\r\n Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms Accept-Language: en-au\r\n Via: 1.0 sydcache:3128 (Squid/2.3.STABLE4)\r\n X-Forwarded-For: 192.168.21.111\r\n Host: www.smh.com.au\r\n Cache-Control: max-age=172800\r\n Connection: keep-alive\r\n \r\n

Now as you can see the HTTP GET request has been changed, it is not passing the URL that was typed in http://www.smh.com.au/ , it has replaced it with a /

My question is why is it doing this, and what can I do to fix it?
