Just a thought:

We ran into problems with Athena and the releases from nevow after
SVN 13786 (was a major upgrade) and IE due to the following policy MS introduced: IE seems to limit the connections allowed to 2max, which blocks IE when for instance running the Athena calculator sample and doing a page refresh or two.

Hmm, not sure we can blame M$ for that. Think I saw somewhere that some standard talks about _2_ connections, only some browsers improve it a bit...

It seems that tearing down athena and bringing it up again may in some cases 'hang' IE (socket states is TIME_WAIT) for around 120 secs. The same happens when going from one livepage to another.

I am writing this on a hunch and from memory, apologies if the problems are not related.

I think they probably are, because of different event handling in IE vs FF.

Our solution for this particular problem was to hang back on SVN rev 13786 for nevow until fixed. Server runs ok with several hundred LivePages connected.

Good to hear it scales well. Wouldn't expect anything else from Twisted, but we're pretty much Nevow rookies here ...
