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...
Just get me right, I'm not blaming MS, but the behavior of IE is erratic
in this particular case. The whole Athena/IE system is also working
logically correct, but the user experience is more than disturbed by the
seemingly dead IE which springs into action after two minutes or so.
IE introduces a hard limit of two connections, whereas FF implements two
open sockets and ignores sockets which are in TIME_WAIT, waiting to be
teared down completely.
AFAIK there is no solution to this problem, because closing a socket
brings it into the TIME_WAIT state
http://www.developerweb.net/forum/showthread.php?t=2941
and what is left is up to the interpretation of the RFC by the
implementor of the browsers TCP/IP code.
The easiest way to illustrate this problem is to run examples.tac and go
to the calculator (example is broken, I proposed a fix on divmod dev
mailing list)
Line 27 in calculator.html from
getElement('output').innerHTML = expression;
to
document.getElementById('output').innerHTML = expression;
Hit the example/calculator with IE and refresh the page...
You will be greeted by a IE which shows the watch cursor and does not
refresh the page until the TIME_WAIT time (usually 120 secs) for the
socket over.
