Program works only on Fiddler

[Kirill]

Hi! I've made a program on C# and it's work perfectly but stops on POST method to the page. When I use Fiddler as a proxy there is no errors. So I would like to know, what does fiddler to with my POST query so it works? What does Fiddler do with it.

Problem solved. My program doesn't close getresponsestream and Fiddler fix it. Now it works without fiddler.
