Hi, Amos !

ignore_expect_100 could be the reason. Exchange tries to use
Expect:100-continue feature sometimes. Your browser may be timing out
before it sends POST'd data.
Although that said, the above POST look to be part of an NTLM
handshake and only taking 150ms.
Without ignore_expect_100 we get
1331073616.344 0 207.46.14.62 NONE/417 4157 POST
https://g1.xxx.de/EWS/Exchange.asmx - NONE/- text/html

https://g1.xxx.de/EWS/Exchange.asmx - NONE/- text/html
But how can I find out what might go wrong ?
What could go wrong with ignore_expect_100 OFF is the client displays
an error page instead of retrying with HTTP/1.0 format request like it
is supposed to.
What could go wrong with ignore_expect_100 ON is the client waiting an
annoyingly long timeout before anything happens. Exactly the behaviour
you noticed earlier.
