[Mapserver-dev] redirect

[Steve Lime]

This probably is a question for the main list, more opinions. I've tried
this myself with limited success as well, but that was because I had
multiple services on one machine to foward to another machine and Apache
doesn't allow you to do any matching (i.e. RedirectMatch) on the query
string. You likely have the same issue since you need to modify the
query string to change directories. My solution was to redirect to a
perl script instead where I had more control over matches on query
parameters. 

In httpd.conf I have:

RedirectMatch /cgi-bin/mapserv$ /cgi-bin/forward_mapserv.pl

and forward_mapserv.pl looks like:

----------------------------------- BEGIN SNIP
-------------------------------------------
#! /usr/bin/perl -w

use CGI;

# Script to forward old calls to /cgi-bin/mapserv to
# the write spot in the CMS. Mainly to support embedded
# calls in a few LMIC applications.

$query_string = $ENV{"QUERY_STRING"};

$cgi = new CGI;

if($query_string =~ /photos.map/) {
  $query_string =~ s/photos\/etc\/photos\.map/AIRPHOTOS_MAPFILE/;
  $url =
"http://www.dnr.state.mn.us/airphotos/browse.html?".$query_string;
} elsif($query_string =~ /view.map/) {
  $query_string =~
s/%2Fusr%2Flocal%2Fwww%2Fdocs%2Fcompass%2Fview\.map/COMPASS_MAPFILE/;
  $query_string =~
s/\/usr\/local\/www\/docs\/compass\/view\.map/COMPASS_MAPFILE/;
  $url =
"http://www.dnr.state.mn.us/maps/compass.html?".$query_string;
}

print $cgi->redirect($url);
exit 0;
----------------------------------- END SNIP
-------------------------------------------

Works ok for me...
