What is the HTTP Header?According to the HTTP protocol specification each HTTP request/response consists of an HTTP header, and optionally from an HTTP content.
When your web browser requests a web page from a server, it sends an HTTP request to the server and provides a wide range of important information about itself and your computer in the request's header. This information includes the browser name and version, the requested URL, the HTTP method (GET, POST, PUT, DELETE, etc), supported languages and encodings, present web site cookies etc.
The web server then replies with an HTTP response and returns the requested web page in the response's content. The HTTP header contains important information about the type of returned data (HTML, image, CSS, etc.) and how to process it (content encoding, length, etc). Server platform name and version, web site cookies, error codes, etc. also are returned in the HTTP header.
Viewing and analyzing the HTTP Headers
The HTTP Debugger is a software program that allows IT professionals to intercept, view and analyze all HTTP headers and content sent/received by your computer to/from the web server. It automatically processes intercepted HTTP headers and shows the most important HTTP header parameters in the Summary Pane of the program.
