Thematic map on the fly

[Xuefeng Wen]

Hello All,

We have a Java web application which needs to use MapServer. Our front end
code can get all the geo IDs (i.e. state or county codes) and the colors
assigned to them.  Can we just pass these info to MapServer as URL
parameters to generate thematic map on the fly? What the CGI variables
should be?  How to implement the map file?

I am new to MapServer. Any help is most appreciated!
