ok source here ftp://ftp.rfc-editor.org/in-notes/rfc2965.txt

Quote:

To allow caching of a document and require that it be validated
before returning it to the client:

Cache-Control: must-revalidate, max-age=0

* To allow caching of a document, but to require that proxy
caches (not user agent caches) validate it before returning it
to the client:

Cache-Control: proxy-revalidate, max-age=0

* To allow caching of a document and request that it be validated
before returning it to the client (by "pre-expiring" it):

Cache-control: max-age=0

Not all caches will revalidate the document in every case.

the ntl proxies arent doing this.

Quote:

HTTP/1.1 servers MUST send Expires: old-date (where old-date is a
date long in the past) on responses containing Set-Cookie2 response
headers unless they know for certain (by out of band means) that
there are no HTTP/1.0 proxies in the response chain. HTTP/1.1
servers MAY send other Cache-Control directives that permit caching
by HTTP/1.1 proxies in addition to the Expires: old-date directive;
the Cache-Control directive will override the Expires: old-date for
HTTP/1.1 proxies.

not sure if still the case but before the proxies werent http 1.1 compliant introducing the above situation

That's pretty obscure at best, and I would think they are all http 1.1 now anyway so doesn't apply.

- of course any things like that are also down to the software they are running, which would be the 3rd party standard software supplied with them (and yes, configuration of that software as well, but I doubt the above is a config option). I do however strongly suspect that many of their issues are config issues, they don't seem to have any consistancy across the country.

agree half of it is config issues the other half (performance side) is lack of investment in more hardware.

they could also disable proxies for specific sites such as dnsreport that arent proxy friendly.

Ironic thing with DNSreport is that its sister site, DNSstuff, actually shows the client IP address of the user (top right corner), but will still ban it if it gets too much traffic from the local ntl proxy....weird ??

I've discussed this possibility with the NTL executive office. Not a chance!

NTL would rather we suffer the problems until they can 'fix' the proxies. The right way of dealing with this problem which has been going on for months is to disable the proxies until the situation is resolved.

That is of course my opinion. NTL would not do this and they have made it 100% clear to me. Hope you get this message before it's deleted...

I dont think they saving that much cash with them, most web browsers by default will cache static images etc. anything dynamic shouldnt be cached by proxies anyway so they probably not saving that much traffic.

Its like a bad smell that comes back all the time and you never seem to get rid of it completely.

He's on about his 8th username here now, and he keeps e-mailing us (mostly me) as well, he's even registered on another site just to e-mail me.

How sad and pathetic - a classic internet stalker.

What i cannot understand is how he can get so upset about the proxies, Ok they are crap but hey there are more important things going on to worry about.
