Google Analytics, SmarterStats, Mint.. they all use client side script to do tracking.

Does that also apply for those with cookies disabled? The client side scripting that is.

RE: the caching thing, didn't know that. I wonder what is meant by ?(b) complies with any conditions imposed by the copyright owner of the material for access to that material; and" is this for specific written warnings to an ISP? I couldn't imagne much else if it's done automatically.

The conditions are part of the http standard - no cache means just that. and expires means just that - you can cache it until this time at which point you must revalidate it, the failure of the revalidation meaning its gone, so that as long as they dont serve stale nonvalidated hits from the cache or cache things explicitly served with no-cache then they are legit within those very simple rules that exempt them from the copyright regs. I imagine thats how slingshot are getting away with the torrent cache - untill they get a complaint about it, it fits within the rules as the torrent's contents will never become unavailable.

Yes, it does.

It means ISPs have to follow the directives returned by the server regarding cache management, expiry as discussed earlier in this thread.

I could see this coming as it seemed like a logical step, saves Telecom on international bandwidth

If you can cache it locally then might as well, seems pretty sensible to me

If it works fine and I see better speeds because of it, then I say go for it!

Non-system disk or disk error. Replace and strike any key when ready.

Have been wondering this for ages. Why it took so long to implement at Telecom.
I am impressed they havent had the same problems as slingshot have had with the caching of dynamic content then serving it to other customers.

Good on Telecom. Performance boost for the masses. It's a good thing!

I agree with tonyhughes, good on you Telecom - I have a feeling Telecom will get this setup right with none of the problems which have plagued other ISP's when they put in caches, like reserving up dynamic content, or the cache servers being under spec'ed.

Or... The cache licenses expiring (slingshot) on the weekend, and blocking all content.

I'm on Big Time so I assume I'm already using the caches(?) as this is what they meant by then extending it too other users?

If I'm using a caching server I wouldn't even know everything works fine. Perhaps I'm not. Hmmmmmm.

Now, the real question is, when are they going to get some of these...

In the last week or so latency to the US and AU has degraded, Telecom doesn't have the setup quite right yet imo.

Example: Ping to the US

During the day: 150-200ms (normal)
6pm-2am: 300ms-400ms+ (100% increase!)

I suspect the traffic management gear or the caching hardware is struggling with the load of tracking so many concurrent user sessions during peak time.

Alot of gamers playing on AU and US servers have been reporting the problem so it will be interesting to see how long it takes to fix.

For the record NZ latency is completely fine and every thing else about the plan has been acceptable to me so far.

I understand that Telecom are using the same cache appliances as the other ISPs, so expect the same problems. It is easy to tell when they are in, as sessions time out at busy times, so over the last week they have mostly been out. These caches are proxies and a proxy is a session breaker, all this to make a few URL's work better, crazy idea.

I was under the impression they were using a combination of

Allot, Akamai and BlueCoat for their traffic management and caching, i wouldn't be suprised to see them also using some peerapp gear either.

Ping is completely irrelevant. The cache only deals with HTTP requests, not ICMP echoes (which is what ping is). They don't magically reduce the connection latency or anything, they just speed up HTTP by retrieving locally cached copies of the response rather than fetching it from the upstream.

The main problem with these proxy caches is vendor software reliability and stability, when a cache crashes 19000 sessions will die, so how much gain to how much pain, only time will tell.

If you have a requirement to fresh news on youtube on the big-time plan you will be surely disappointed, just trying to watch the latest on the US open, and all I get is that spinning circle, so try again in 24 hours and hope that somebody else likes watching that spinning circle.
