Down and dirty with Trace Listerners for SOAP Messages

Recently I was trying to implement a web service call for a client who had another firm implementing a very secure web service using client certificates (Ill blog about how to get that working sometime soon). However once Id got the security sorted I was getting a Method not allowed 403 error in order to diagnose the problem I needed ot get at the raw data travelling across the wire. as it happens dot net has a brilliant diagnostics suite which is really simple to implement. Simply add the following into your web.config file underneath the system.web node and presto youll get a trace.log file will all that lovely low level info in!
