No, although I think this should be supported. Would be easy to do, just need to define the way to trigger it. I may have even proposed a way to do this in an old RFC and just neglected to implement. Will tackle as part of RFC44...
BTW Bill, your syntax is wrong below. 5.x uses something like: map.layer[name].class[0].style[0]=COLOR+255+0+0+OUTLINECOLOR+0+0+255 Steve >>> "Martin Kofahl" <[email protected]> 01/05/09 6:54 AM >>> An additional question: can I forbid overriding of map file parameters via form or url?
