 Mozilla tcpdump: Note that this worked perfectly unlike the tcpdump above when I used IE.

+This appears to be a TCP/Socket level issue.  I looked at the actual 
+TCPDump in Ethereal and noted the follwing:
+
+* When it works: at the end of the exchange both ends send a request 
+[FIN, ACK] followed by an [ACK] response.
+
+* When it fails: it appear the web server is sending a [RST, ACK] 
+and immediately terminating the connection, because it thinks the 
+web browser (IE) has sent a [TCP Dup ACK].
+
+This is obviously quite a low level networking issue in MONO or XSP, 
+and thus would not appear using Apache where it is doing the network 
+stuff.
