    Intercepting Data Bound for Local Application from Remote Server

    Hi, im an online gamer and I want to filter out certain things from the game chat room before they show up on my screen, like certain explicit text and the like. Is it possible using the Windows API to route data bound for a java applet in my browser to a point where I can filter it first, before it goes to the applet? I hear something called loopbacking may help, but I'm not sure how that works.

    There is nothing in the Windows API that can help you, but writing a LSP would do the trick. The problem is finding good information on how to write and install a LSP. The last time I did this, it took me weeks of painful trial and error to get it right since I couldn't find much in the way of documentation. The website that got me started was this one. As far as I know, this is the only way to do what you are attempting to do in the realm of user space. Obviously writing kernel level programs (drivers, filter drivers) will also solve this problem.

    You could also consider writing a proxy server (which would run on the same computer as the client). Assumably, this is what is meant by "loopbacking".
