Apache offers an open source multithreaded HTTP Server that can integrate with Oracle.

The Oracle Database can work with either Apache 1.3 or Apache 2.0. The integration is done via Mod PL/SQL. The Mod PL/SQL with Apache 1.3 superseded the previous integration Oracle provided when it provided its own web server.

The multi-threaded nature of the connection means that Apache establishes a number of fixed connections to the database (client/server). Multiple HTTP users then perform requests on a round robin type basis across these fixed connections. This means that there is no guarantee that if a user performs multiple HTTP requests, they will be using the same physical connection to the database. This is a key issue that has to be considered in the development. It means that the PL/SQL program (or Java program) cannot rely on session variables or the content of temporary tables to be there from call to call. Apache manages the load balancing and based on the usage can increase...
