Our C# application uses embedded IE - we use AxWebBrowser. When we call Navigate2() the first instance will typically open the web content with no problem. But soon after, the website opening in other instances of AxWebBrowser will slow down to the point that the content will not render at all.
It seems like the slow-down/no-load scenario happens only when I am connected to my corporate VPN. Standalone IE does not experience the same problem and it will load the same pages in no time even if on vpn. The websites are hosted on local IIS and there is no single issue at all. I tried replacing AxWebBrowser with WebBrowser available as native C# control but the result is the same.
I tried replacing AxWebBrowser with WebBrowser available as native C# control, but the result is the same. The tests run on Win7/64 and IE11 although the C# app is x86.
Any help or clue would be greatly appreciated.
Thank you.
