OK, I have an internet filtering application that I have inherited. The current application does the internet filtering via a direct interface with Internet Explorer thus it does not work with FireFox or other non IE browsers. So, I have been researching for days. I have not come to a clear solution on how the existing content filtering applications may have implimented there filtering. Does anyone have experience writting an application that will filter internet content regardless of the internet browser. I would like to display a very simple Access denied type page in the browser. Just filtering based on the URL to start with would be good. I am very open to using any language and comfortable with C++. Just seems that there are a large number of applications that already do this and I would be supprised to find that they are all using something like a TDI Hook DLL, Winsock LSP, etc... Just seems there should be an exposed API. I really do not want the user to have to set proxy settings, I am still researching a silent/in-visible proxy server and looking into a Filter Monikor but, any suggestions on doing this would be much appreciated. I am getting a little frustrated that I have not been able to find good information for doing this, Like I mentioned there are a ton of applications already doing this so it seems that I am missing something simple.
