My understanding of server-side maps just took a hit as I was checking out the details if my favorite server-side map at http://www.metrokc.gov/. The code for the server side map at the top of the page is: <a href="http://www.metrokc.gov/wwwnav.map"> <img src=" ..." ... alt="King County Navigation Bar (text navigation at bottom)" width="586" height="41" ISMAP vspace=4> </a> The thing that baffles me is the href (http://www.metrokc.gov/wwwnav.map) here is just text file which you can check; here's the contents: <start wwwnav.map> # links for KC navigational header http://www.metrokc.gov/ # home rect http://www.metrokc.gov/ 45,4 135,39 # news rect http://www.metrokc.gov/news.htm 141,4 232,39 # services rect http://www.metrokc.gov/services.htm 238,4 345,39 # comments rect http://www.metrokc.gov/go/comment.cfm 351,4 480,39 # search rect http://find.metrokc.gov/ 485,4 583,39 <end wwwnav.map> And if I simulate w click by submitting http://www.metrokc.gov/wwwnav.map?142,5 by just opening it in my browser, indeed the News site is opened. Why? What is special about the .map file on the King county server that it knows to open a page depending on whether the coordinates are in corresponding ranges. I can figure no reason for this to be a server side map, but if what I find here is generally used, there is even less reason since the data for a client side map exist in the .map file on the server.
