Application: Traf

Traf monitors a file for modifications and copies the modified file into archive rotation. An external program of your choice defines the frequency of the file's modification, which in turn dictates the number of archived files that are stored before they expire. Traf, along with the accompanying ssiEmbedLatest.cgi, are an ideal solution for WebCam push. Your WebCam software updates the image on your Unix server, the script detects the source file's modification and copies the image file into archive rotation. When used with an SSI web page (.shtml), ssiEmbedLatest.cgi will retrieve the most recent files from the archive directory for display. Each image file name is tagged with the date and time of it's creation. Each time the web page is reloaded the latest images are embedded in the page, with names different from the last reload, thus eliminating image caching subtleties between browsers.
