[mapserver-users] mapserver files to subdomain results in '500 Internal Server Error' when mapserv executable accessed through url

[Ted Spradley]

Thanks Andy.

Yes, changed mapserv to a different name, and both 404's.
access_log:
 - - [21/Sep/2009:21:35:25 -0500] "GET /cgi-bin/mapserv HTTP/1.1" 404 1464 
"-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-     US; rv:1.9.1.3) 
Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)"
 - - [21/Sep/2009:21:35:33 -0500] "GET /cgi-bin/mapserv HTTP/1.1" 404 1464 
"-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-     US; rv:1.9.1.3) 
Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)"

I am not sending any parameters at all through the url, only checking 
functionality.

1. http://domain.com/cgi-bin/mapserv
2. http://maps.domain.com/cgi-bin/mapserv

Apache does have different virtual hosts for each, but the access_log above 
shows each request getting converted to the identical GET request.

1. 'http://domain.com/cgi-bin/mapserv' -

[21/Sep/2009:12:40:12 -0500] "GET /cgi-bin/mapserv HTTP/1.1" 200 249 "-" 
"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 
Firefox/3.5.3 (.NET CLR 3.5.30729)"

2. 'http://maps.domain.com/cgi-bin/mapserv' -
[21/Sep/2009:12:40:20 -0500] "GET /cgi-bin/mapserv HTTP/1.1" 500 1549 "-" 
"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 
Firefox/3.5.3 (.NET CLR 3.5.30729)"

One gets code 200, Two gets code 500.

All of my openlayers, mapserver, etc programs function normally on the main 
domain.

I even tried moving around the SetEnv directive to outside the 
<directory></directory> in both httpd.conf files

Thanks again for all of your thought.

Ted S.
