In cases where multiple values are associated with a variable (eg.
mapext), the values must be seperated by spaces (or their escaped
equivalents for GET requests).
Variable contents are checked for appropriate data types and magnitude
as they are loaded.
Any CGI Variable not listed below is simply stored and can be
referenced within a template file.
Modifying map parameters through a URL has changed to allow for
chunks of a mapfile to be modified at once. The syntax has changed
accordingly, so please see the Changing map file parameters via a form or a URL
section.
New way to perform attribute queries: No longer do you set a layer
filter, but rather you pass a query string (and optionally a query
item) to the query function. To do this two new CGI parameters were
added to MapServer: QSTRING and QITEM.
SAVEMAP is switched off: The SAVEMAP functionality is considered
insecure, since the saved files are accessible by everyone.
TEMPLATE has been removed, since the map_web_template syntax can be
used to alter a template file. Simplifies security maintenance by only
having to deal with this option in a single place. Note that the
TEMPLATEPATTERN of the mapfile has to be used to enable this feature.
