But why do you need to do this? If it's related to testing (or even if it's not, this may provide you with something you can use) you can look into combining HttpUnit and JUnitPerf. Both are extensions of the JUnit framework - HttpUnit provides classes for easily working with HTTP requests/responses, and JUnitPerf deals with performance related topics, but would mainly be interesting to you because it provides an easy way to repeat tests on a schedule.
