HTTPSniffer

HTTPSniffer is a feather-light application designed to keep track of all traffic that goes through the HTTP protocol, enabling you to analyze various types of information, such as header values, cookies, query strings and error codes.

The setup operation is a fast and simple task that shouldn't cause you any trouble, thanks to the fact that it contains only familiar options. Once it's over, you are greeted by a plain and simple window that contains log details.

After specifying a program to debug (web browser or otherwise), HTTPSniffer will start monitoring tracking and adding entries to the list, revealing their origin, URL, content type, status, sent and received packets (in bytes), and total time.

You can check out the full header and content details of HTTP requests and responses, get requests from installed plugins like ActiveX or Flash, as well as examine captured images, HTML or XML code from the built-in web control. Any automatic redirects made by the browser are automatically recorded by HTTPSniffer.

The entire information or just a summary of the traffic can be exported to log files (.log format) for closer inspection. Apart from the fact that you can clear all data, there are no other notable options supplied by this software program.

HTTPSniffer didn't put a strain on the overall performance of the machine in our tests, using low CPU and RAM. However, it hasn't been updated for a long time, and it's not fully compatible with the latest Windows editions. You can still use it if you're running older Windows, though, such as XP.
