ServiceCapture is a tool designed for developers to help them to debug, to analyze and to test an application. It captures all HTTP traffic of a computer such as data received and sent by a browser, by instant messaging, etc. It scans all traffic passing through port 80. It is possible to perform simulations according to the user's connection (56K, ADSL, cable, etc.). The best way to find out and get an idea about its capacity is to download and try it.
