You can't do this at present. Sorry.

Subject: [mapserver-users] Change a SYMBOL param via URL (CGI MapServer)

I want to change the POINTS values in a SYMBOL defined in my map file. Can
you do this on the fly?

i.e. I define the symbol in the map file:

MAP
.
.
SYMBOL
  NAME mySymbol
  TYPE ELLIPSE
  POINTS 1 1 END
  FILLED TRUE
END
.
.
END

In the URL I have tried both:

...&map_symbol[mySymbol]=POINTS+2+1+END&...

and

...&map_symbol[mySymbol]_POINTS=2+1&...

Neither results in a parse error, but they don't change the aspect of the
ellipse either.

Can it be done?
