Content Summary :
In computer systems, communications protocols are guidelines for formatting the messages sent from one hardware or software component to another, for example, from a client’s web browser to an application server. Since effective communications cannot occur without an agreed upon format, the communications protocol is key to successful communication in any interaction involving computer systems. The most important communications protocol for all web applications, including those built using Oracle products, is Hypertext Transfer Protocol (HTTP). In fact, web application servers are HTTP servers, so HTTP is the heart of applications running both on the World Wide Web and also on organization-level application servers. The mechanics, features, and constraints of HTTP communications are usually a bit of a mystery to those accustomed to working with client/server and terminal mode applications. Even those who have worked in a web environment and have a concept of the HTTP communications path may not have studied HTTP in detail.
