Web developers locate and eliminate website errors analyzing http request and response cookies, authorization headers, POST parameters, error codes and http content data.

For each web page analyze the number of produced http requests and responses, its size, downloading time and speed.

Software developers view http requests sent by own programs (C#, Java, VB, C++, Delphi, etc) and server responses. Analyze each http request and response produced by a web browser add-on, ActiveX component or Java applet. See http headers and http content data sent/received by Windows System Services.

System and network administrators monitor all outgoing http requests from your computers. Analyze each http request and http response to see what data is sent by programs to the Internet.
