IWebBrowser2 and socks4/5 proxy

Question

It seems that web browser component (Windows 7, IE11) can't browse at all in case it's specified by a user in settings to use socks proxy. Internet Explorer works, my application based on web browser component can't browse any site - I got network error. Sample application from MSDN acts the same way as my app. Any suggestions?

Answer 1

SOCKS4 works for me. Form your app, check if the correct proxy setting is there, with UrlMkGetSessionOption / INTERNET_OPTION_PROXY .

That said, most likely you're dealing with some firewall/antivirus software which is configured to allow SOCKS requests from a certain white list of approved apps (including iexplore.exe ). Your app is not on the list.
