From the developer: "Trace the low level communication between your browser and a web server. See the HTTP commands, and server responses. You can see response time and byte counts, and get file names that are downloading. HttpTracer is a web tracing program that captures communication between a browser and web server in the native HTTP syntax. HttpTracer acts as a local proxy and captures HTTP browser Requests and the Server Responses (including headers, response codes, html, java script, css files, xml, graphics file names, etc.). HttpTracer breaks up browser session into request/response conversations and shows all text commands and data returned to the browser. It shows response times as well as the number of bytes transferred. Use this information to build automation routines, capture file transfers, measure response times, and analyze web applications network traffic."
