Grzegorz Daniluk’s, Full-Duplex Ajax (FdAjax) is an extension of the Ajax technology. It allows to initiate communication from the HTTP server to the browser and therefore enables to easily create efficient solutions like web chats. It is the server that sends new messages to the browser when they appear. Normally the browser (JavaScript code) has to periodically check if there are new messages and send queries to the server. This is very expansive and causes delays.

FdAjax is used on Refwell. Thanks to FdAjax, in most cases, you only have to click twice to get your help on Anslive. In order to find something on Google you have to click once. And in order to perform a much more complicated transaction between two users on Anslive you only have to click twice. Check it out. Watch our Anslive video tour.

FdAjax is implemented as a module to the great Lighttpd web server. No additional components are needed. Therefore the configuration is easy and unified. E.g. you have to configure the SSL communication and the access control in the configuration file only once, it will also apply to the communication with the FdAjax module.
