The Request for Comments (RFCs)

The Requests for Comments (RFC) documents are papers specifying different aspects of the Internet. They can be technical and even funny. They describe how to define computer networking such as protocols, programs and concepts. When a new internet-related functionality emerges a RFC is written and after debate, trials and thorough investigation the functionality is elevated into an official internet standard.

This following list shows the corresponding RCFs that Simple Failover uses to probe for available web server functionality.
