I received today a question often asked about WebWait, so I’ll answer it here for reference.
WebWait User asks:
I have been using webwait for a while and have a quick question for you. When running multiple calls on the same website, is each call downloading the entire page again, or is the information being loaded from the browser cache?
It will do whatever the browser would do if the page was loaded normally, so that would usually mean the 2nd-Nth time it will download from the cache. To counter-act that, you can simply disable your browser cache while performing your tests. Or if you do want to test cache performance, just open your site once (either in the browser or WebWait) and then start the WebWait tests, obviously keeping the cache enabled throughout.
