WebApp is a Delphi-based development framework for Web server applications. Applications written using WebApp are always stand-alone executables, running outside the server's address space. This fact ensures that a bug in the application does not bring down the entire server, a danger inherent in DLL-based server extension standards such as ISAPI, NSAPI or WSAPI. The interface between the Web server and the WebApp application is implemented using a small protocol-specific stub. The purpose of the stub is to perform as a safe gateway between the Web server and the application. The request from the server and the response from the WebApp applications are relayed using an efficient in-memory inter-process communication protocol.
