Hi..

Make sure that you restart the application after changing your proxy
settings.. 

If this (or the other suggestions) dont work, check out the
outstandingly useful echomirage from bindshell.net

Thanks guys for the suggesstion. I tried doing this and for some reason the 
although Paros works for IE, it does not work for the thick client 
application.

The thick client seems to send the traffic directly.

Any other suggesstions?

Hi Huan..

Fortunately for you, a .Net application will make use of the proxy
configured on the system when making SOAP calls by default (because i
believe it is using an IE instance to handle the call).

Simply set burp/paros as your proxy prior to starting up your
thick-application and it should work exactly as you planned..

(if the app bails because of an incorrect SSL key, you might have to
decompile the binary to remove the cert check or may get away with
installing a new cert (with just the correct CN into paros/burp) - but
you can contact me off-list if this does happen)

List,

I am testing a .NET thick client application using web services. I am 
looking for an HTTP/TCP Proxy tool like PAROS / BURP which I can use to 
see the change the traffic. The application does not have a way to set 
proxy setting so I cannot use paros / burp and then do proxy chaining. 
Also, everything on the tunnel is SSL, so ethereal is not much help

Also, any good tools to edit XML / SOAP traffic

Thanks for suggesstions in advance
