FilterPlus? is a unique and revolutionary IIS filtering product which lets ASP and web site developers accomplish web site access control, request filtering and monitoring/logging quickly and painlessly. Previously this has been accomplished by using C++ to create IIS filters, but with FilterPlus? you can perform all of these tasks by using filters which can be written in ASP. (You may also use ASP+, Cold Fusion, and CGI/Perl as well).
