Thank you very much to Steve Line and Carlos Ruiz for your feddback and
suggestions!
Finally I get the solution using mod_rewrite, and this is the solution that
work in my case:
RewriteEngine on
##LogLevel alert rewrite:trace5
RewriteCond %{QUERY_STRING}
^[A-z0-9,.%/-?&=]+GetFeatureInfo[A-z0-9,.%/-?&=]+
RewriteCond %{QUERY_STRING} ^(.*)raster_to_display(.*)
RewriteRule ^.*mapserv.exe.*$
http://localhost/cgi-bin/mapserv.exe?%1vector_to_query%2 [PL]
Best regards,
Anna
