Funny timing. Just yesterday I was looking for an easy Windows tool to do a simple stress-test on a website (legally ofc). A requirement of mine was to just give it the root URL and the tool should discover the rest automatically (staying on the same domain). Also, parameters like parallelism had to be easily manageable. After trying some crawlers / copiers and other tools I went back to a simple one I already knew from saving static copies of websites in the past: HTTrack. It fit the bill perfectly! You can add the root URL, set it to "scan only" (so it doesn't download everything) and tweak the settings like connections and speed (and even change some settings mid-run, save settings, pause, ...). So thanks xroche for HTTrack! :)
