Ed,
I have attached an email from Daniel Morisette about the BUG 302 he =
posted awhile back about this.
I think I am probably familiar enough with C code to fix this "bug" or =
to enhance mapserver but would like some help in any event.
Would someone on this list be willing to post a VC7 (.NET edition) =
project file so that I could start the process to "enhance mapserver".
Thanks Stephen

Stephen -
The HARD CODED number is easily changed in map.h, and a rebuild can make =
the number any size you like. There are some performance advantages to =
the current implementation, so deciding to call it a "bug" doesn't make =
it one <g>. One can make a good case for either the current scheme or a =
"all you can load" scheme - the biggest disadvantage to the current =
implementation is that if you're not already set up to rebuild MapServer =
it can be a bit of work to make a rather simple change.
