What are FrontPage extensions?

FrontPage Server Extensions are a software technology that allows Microsoft FrontPage clients to communicate with web servers, and provide additional functionality intended for websites. Frequent security problems have marred the history of this Microsoft proprietary technology.

FrontPage extensions rely on HTTP protocol and CGI/POST for server side processing.

FrontPage extensions were retired by Microsoft and are no longer considered secure. We recommend PHP and JavaScript over the FrontPage extensions. The Microsoft FrontPage web publishing software has existed for over 20 years, with mainstream support dropped on 4/14/2009, and with extended support ending on 4/8/2014.
