I have thought about using tilecache with metatiling, however there is a caveat about this map that i forgot to mention in my main post, and it has to do with that "categories" parameter. Basically, each point/symbol on the map has an associated category in the database backend. I am using mapserver/WMS parameters to change the categories which are called. Each time the user selects a category, only the points in that category are shown. My query in the mapfile looks something like thi:
SELECT point_geom,gid,symbol,angle FROM mapdata WHERE category IN(%CATEGORIES%)"; And each time the user changes the categories, I use openlayers to merge new parameters, and input the new category values that should be used. Is tilecache still useable if I have a system like this set up?
