ciscofriend,

 

A couple of things, the default HTTP monitor users HTTP version 0.9, rather than 1.0 or 1.1. You could try and change the monitor to use either of the later versions of http, see Constructing HTTP requests for use with the HTTP or HTTPS application health monitor

 

Also, what happens if you do tcpdump, does this give any clues?

 

tcpdump -nni 0.0 -s0 host x.x.x.x and port 80

 

Hope this helps,
