This is a gif file generated by use of the GD-Graphics capability built into NeoWebScript. This little demo uses the the newest "Server Caching" feature that Randy just added - NEAT STUFF! NEW 4-1-97 Just added code to the .gd file to generate a client-side imagemap along with the gif. The imagemap contains one hot-spot for each data value plotted. The spots all link to the JAVA demo of Hourly Visitors & Accesses for the day to which the data value applies. (No - not an April Fool's Joke - and tested with IE 3.01 and Netscape 3.01 - older/other browsers may work for a client-side map that follows the image) NEW 7-18-97 Just added a little JavaScript display of the date of a data sample when the cursor is on a link in the image map.

The source used to generate the .gif (and imagemap datafile) is a bit more complicated than is really needed and could be greatly simplified for cases where there are fixed scales and labels and such; however, this implementation is very general and is very easily modified for longer time intervals and value ranges etc. Also, the getData() proc may seem a bit obscure - but don't let it throw you.

Anyway, the demo illustrates how to set the expiration time of a generated gif. Gifs generated using this feature are cached on (an by) the SERVER. Once generated and cached, subsequent requests before the indicated expiration time cause the server to simply return the cached copy of the gif. The expiration time is also sent as a header in the gif itself so that client caching will not cause problems - this is a really neat and helpful characteristic and Randy deserves a big ATABOY for this one for sure!
