The link below shows you how to use Fiddler2 to trace how TortoiseSVN communicates with SVN Bridge.
TortoiseSVN is a well known SVN client that nicely integrates with the Windows Explorer shell.
SvnBridge sits on top of TFS so that you can use Subversion clients against Team Foundation System.
The settings are so that only the TortoiseSVN requests are captures.
Basically the trick is to start Fiddler2, have it stop capturing WinINET traffic, then modify the TortoiseSVN uses Fiddler2 as HTTP proxy.
Here are the details: SvnBridge – Use TortoiseSVN with Team Foundation Server.
Hope this helps a few of you debugging the TortoiseSVN path to SvnBridge.
