Script for SUSE Linux

I need help for coding an executable script for SUSE Linux that opens a specified website multiple times simultaneously for a period of time in the background to simulate a situation where multiple simultaneous users accessing the website. This is for testing purpose of my High Availability cluster project (everything in VMware) to see whether there will be resource fail over when the server cant handle the load anymore. A simple coding and steps would suffice and i will create the executable myself in my Linux machine.
