hi, i'm buildin an app like the trace utility provided by MS, so what i did was to try out Pramod Singh's http://www.c-sharpcorner.com/internet/web_proxy.asp. sadly, it didnt go down too well. it can't communicate w the web service v well. it is somehow erratic. is it because it is using sockets instead of some sort of http handlers? No offence Pramod. i stuck the trace utility between the app and the web service. sometimes the trace utility would show the response from the web service but somehow the app doesnt rec it.
