I was also facing similar kind of problem sometime back. Our application was using an ActiveX object which communicated with the server using windows sockets. We were not given details about this socket level communication which in turn resulted in pure HTTP functions alone getting generated. We were completely unaware of this. But Ethereal helped us to find out that the application is using Sockets along with standard HTTP communication. It helps especially you have something not communicated to you by the development team :-)) Thanks for the information. I was also facing similar kind of problem sometime back.

Network admins get very, very nervous when an Ethernet connection goes into promiscuous mode on their network, it is very detectable. Make sure you understand your company's policies on this sort of thing before you crank up any kind of non-proxy packet sniffers. Having a good relationship with the network admins helps too. For instance, I made arrangements once that there would be only two hosts *ever* running Ethereal or similar tools, and if the network admin were ever to detect a different host in promiscuous mode, I would help investigate the situation.

I can definitely use this when diagnosing traffic and performance problems. Chris http://amateureconblog.blogspot.com/ Thanks for the heads-up on this one.
