[mapserver-users] Problem with Variable Substitution for EXPRESSION

[Prabu Raja]

Thanks Steve.

Tried the following regular expression

"[-+]?[0-9]*\.?[0-9]+".

For which the internal server error is coming from Apache. No error logged
in mapserver log.  "Internal Server Error

The server encountered an internal error or misconfiguration and was unable
to complete your request."
