WAS is a microsoft's web stress tool available for free @ http://webtool.rte.microsoft.com/ location. This tool i downloaded to do an test on our website currently hosted in a local machine. i did open our site in browser during recording. when i run the script after recording i generate reports. But i totally get socket errors (above 3637 or 5492). My doubt is do i need to run an application server or web server in my machine ? do i need to have a local copy of all the web pages in my machine ?
