Is there any way to hook-up all http requests from all browsers using .NET?

I'd like to have an app which would have access to all requests send from an开发者_如何学Cy browser at the current pc.

I don't want to have any kind of a proxy server,beacuse you have first adjust the browser settings.

Is this even possible using .NET ?

Fiddler has a .NET API that includes an event-based scripting system, allowing you to inspect all HTTP / HTTPS traffic from your machine. It's quite popular; there's even an SO tag for it. Technically, it is a proxy-based system; but because it reconfigures the default system-proxy on startup, traffic from browers with default proxy-settings enabled should be visible.
