[mapserver-users] Rewrite rule problem

[Eichner, Andreas - SID]

Hi Goran,

the RewriteRule should match the Location for SetEnvIfExpr:

  <Location "/cgi-bin/GDZ/wms">
    SetEnvIfExpr "%{QUERY_STRING} =~/^(.*&)?map=([[:alnum:]]+.map)(&.*)?$/" MS_MAPFILE=C:/ms4w/apps/Demo/$2
  </Location>

  RewriteEngine On
  RewriteRule /cgi-bin/GDZ/wms /cgi-bin/GDZ/wms?MAP=MS_MAPFILE [PT,QSA]

And then the URL

  http://localhost:81/cgi-bin/GDZ/wms?map=N1.map&REQUEST=GetCapabilities&SERVICE=WMS&VERSION=1.3.0

should set the MS_MAPFILE environment variable to "C:/ms4w/apps/Demo/N1.map" and rewrite the URL to 
  http://localhost:81/cgi-bin/GDZ/wms?MAP=MS_MAPFILE&map=N1.map&REQUEST=GetCapabilities&SERVICE=WMS&VERSION=1.3.0
This should work as MapServer scans the query parameters from left to right. It first finds MAP=MS_MAPFILE 
and checks if there's an environment variable set assuming that it points to a valid map file. 
The SetEnvIfExpr has set this variable for the URL "/cgi-bin/GDZ/wms" if a "MAP" parameter was provided.
