Hi Chris,
Thanks for your suggestion:
Is the webcache a transparent one, our do you have to explicitly configure your webbrowser to use it.
No, I don't have to configure my browser, so I guess it is supposed to be transparent.
If it is a transparent one, ie NTL intercept all outbound data to port 80 and direct it thorough their cache, you could try the following...
telnet www.ebay.co.uk 80 HEAD http://www.ebay.co.uk HTTP/1.0
Then hit enter twice. If NTL's cache is transparent, you should get an output similar to that below...
HTTP/1.0 200 OK Server: Microsoft-IIS/4.0 IISExport: This web site was exported using IIS Export v2.2 Content-Location: http://www.ebay.co.uk/index.html Date: Sat, 05 Jul 2003 12:05:44 GMT Content-Type: text/html Accept-Ranges: bytes Last-Modified: Sat, 05 Jul 2003 11:54:34 GMT ETag: "0397c33ec42c31:13346" Content-Length: 41168 X-Cache: MISS from gateway.glovercc.clara.co.uk Proxy-Connection: close
I get:
[ian@heron ian]$ telnet www.ebay.co.uk 80 Trying 66.135.192.41... Connected to www.ebay.co.uk (66.135.192.41). Escape character is '^]'.

The X-Cache line is the important one.
If the cache is not transparent, you will not see the X-Cache line.
Cannot see one.
Ian.
