If you need to capture and analyze all incoming and outgoing traffic between a web browser or application that uses the HTTP protocol and its corresponding web server, then SoftX HTTP Debugger is the program you are looking for.
Each HTTP request and response can be analyzed to visualize the values of the parameters of the headers, cookies, strings, the source code of the web pages or scripts, error codes, etc.
All captured pages and their respective images can be viewed in the web viewer integrated into the program itself. All captured HTTP traffic can be exported to log files, both in standard network format and in decoded format (as browsers see it).
SoftX HTTP Debugger has support for the most popular web browsers and all their plugins. Software developers can also use it to analyze HTTP traffic in their own web applications.
You can free download SoftX HTTP Debugger 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
