how to set WebBrowser proxy

Question

I am making a multi-threaded application. Each thread has its own WebBrowser control. I want to know how to set a different proxy for each WebBrowser. A custom WebBrowser that supports a proxy per instance will be a good solution to me as well.

Answer 1

Since the WebBrowser is just an instance of the IE, it is impossible to set the Proxy for it. (Unless you tweak the registry, but it it's not individually)

Answer 2

Maybe another approach would be in order.

You could spawn a WebRequest in the background threads and set a different proxy for each one. After you receive the data, then you can easily load it in a WebBrowser to play with it.

Answer 3

Using unmanaged code it can be achieved, it may help:

Answer 4

As maor said, you won't be able to do a proxy per browser setup with WebBrowser. Instead, if you have control over the proxy, you might want to see what options it has for identifying a session (request/response). You might be able to, from the one proxy, tell which requests are probably coming from which WebBrowser controls depending on URLs and headers, etc.
