HTTP sniffer and HTTP analyzer 4.2

An HTTP sniffer and HTTP analyzer, that allows you to capture, view and analyze all communications between a web browser or any other HTTP related program, and the Internet.

By intercepting and analyzing the HTTP protocol headers, you can retrieve a wide range of information about your web site and web server. Such information includes; used HTTP method (GET, POST, PUT, DELETE, etc), supported HTTP version, supported encodings, used cookies, server platform and version, received HTTP content encoding and length, returned error codes etc. By analyzing the HTTP protocol content you can view submitted HTML form details, HTML/XML web page sources, the code of Java and VB scripts, images and more.

With our HTTP sniffer and HTTP analyzer you can preview all captured web pages and images in the built-in web browser control. All captured HTTP traffic can be exported into the log file either in the RAW network or in a decoded (how browsers see it) format.

You can significantly optimize your web site performance, by analyzing the results provided by the program. For each downloaded HTTP resource (web page, image, flash movie, etc) the HTTP sniffer and HTTP analyzer calculates its size and its download time. You can use this information to pinpoint large web pages and if necessary divide them into smaller parts, and to find dynamic web pages (CGI, PHP, ASP, ASP.NET, Java, Perl, ColdFusion, Python, etc) that perform slowly and need optimizing for speed.


The HTTP sniffer and HTTP analyzer works with all popular web browsers (Internet Explorer, Mozilla FireFox, Opera, etc) and their plugins. Software developers can use it to capture and analyze the HTTP traffic of their own software programs. Moreover, you can simultaneously analyze the same web page in Internet Explorer, Mozilla FireFox, Opera and in your own program, and see the results of all these programs in one single HTTP sniffer and HTTP analyzer window.
