HeritageQuest

Views: I.e., pageviews. A page is defined as any file dished out by a web server that would generally be considered a web document. This includes HTML pages (.html, .htm, .shtml), script-generated pages (.cgi, .asp, .cfm, etc.), and plain-text pages. Image files (.jpeg, .gif, .png, etc.), sound files (.wav, .aiff, etc.), video files (.mov, etc.), and other non-document files do not count as pages. Each time a file defined as a page is served, a pageview is registered by Urchin.
