eValid™ is a general purpose WebSite test engine with all functionality built into an IE-compatible Web Browser. Its main functions are site analysis, functional testing, server loading, and page timing/tuning.

eValid achieves site analysis through use of a built-in WebSite "spider" that starts at a given page and systematically visits all of the links reachable from there, applying various filters to every page along the way.

Site Analysis of a WebSite always involves an initial URL -- the starting point of the mapping process. From the starting URL the eValid Site Analysis engine downloads the initial page and then each page it points to, and each page each of them point to, etc. This is a recursive descent of the sub-WebSite that starts at the initial URL. Searches can take from several minutes to many hours, depending on the the complexity of the WebSite and the eValid Site Analysis engine always produces a detailed and complete Site Analysis -- unless you interrupt the process or start it with constraints.
