I need help..
I am trying to write a windows service using .NET that monitors the http traffic and block loading few JS scripts and show a warning message to the user saying few scripts are blocked due to company policy. And this windows service runs on all users computers. I tried writing a local proxy and started alter every response and inject a html warning message. But the response is delaying and users started reporting slow browsing speed because of local proxy. Is there any other solution tat i can alter the web traffic with out any performance issues?
