I have noticed a few problems since NTL introduced their trasnparent proxy cache to my area. HTTP pipelining often results in half loaded pages, but worst of all is the fact that the proxy cannot always be detected.
Try going to a few different sites that claim to detect if you are using a proxy. Some will detect it, some won't. Try these two:
http://www.all-nettools.com/pr.htm
http://www.broadband-help.com/cm_dia...bhab=-1&init=1
The first says I am behind a proxy and correctly finds my IP, the second says no and returns the IP of the proxy
This makes some sites impossible to use. For example, Tekheads.co.uk. The log-in page detects the proxy, but the catalogue page does not so it looks like your IP changed when moving around the site and you get logged out again. It's impossible to buy anything. Forum sites linked to a BitTorrent tracker don't work either.
Anyone else get this? I emailed NTL but no response, so I'm going to try phoning. Not that it will help, but oh well.
