Hi there, I got bit by the "I must code" bug so I created a Droid app that will crawl a given site and check for broken links or caching issues. It's called Link Triage and it's totally free. Because it's network intensive, it does require a WiFi connection. You just enter a URL and it will begin crawling the links on the site. It will produce a scrollable report about the links, the response code that it received for each link, and whether or not internal links are cached. I do limit the number of links (1000 links if your device allocates 64Mb). It's really meant for micro-niche sites without a whole lot of links. If you need something more industrial strength, you're probably better off using a desktop app or other online service. Feel free to check it out.
