WebScarab .NET SSL Error

Hi Friends,

I am testing a .NET-SSL enabled web application, and i discovered a
possible SQL Injection, then because of lack of space in the input
field of the form, i start trying to use a Proxy like WebScarab or
Acunetix, but after submit the request through this proxies the
application stops responding and i am not able to inject any code.
I think could be because of .NET certificate trust validation, if so?
Do you know how to bypass this issue?

Have you ever been able to test an https .NET application through a Proxy?

Thanks in Advanced.
