I hadn't received the previous email for some reason.  I tried the 
suggestion below but received the following error.

loadProjection(): Unknown identifier. Parsing error near (:):(line 1)

I sent a reply to the list on the 23rd, did you see/try that? The proper 
syntax for
a layer projection is:

  map_layer[layername]=PROJECTION%20init%3Depsg%3A26914%20END

I checked the code and a projection can be modified by URL.
