If you're serious about SharePoint, you know Netmon. Well, if you like Netmon, then meet his big brother Message Analyzer
It's like Netmon on steroids J…
There is a lot to tell about this tool, but I won't. Hey I'm a SharePoint geek, I have better things to do!
What I can tell you is that cool things have been added like payload rendering, statistics views, and proxy capturing (ala Fiddler) which makes our lives a lot easier.
Just take a look at the juice screenshot where I'm peeking in the HTTPs stream of the Connect site. Lovely!!
So get the beta from Connect and do some testing yourself!!!
