[OpenLayers-Users] Control access to WMS

[Robert Sanson]

I have made copies of mapserv.exe in my cgi-bin to other names such as
gsswms.exe. I then have a line at the bottom of httpd.conf:
 
SetEnvIf Request_URI "/cgi-bin/gsswms.exe?"
MS_MAPFILE=/ms4w/apps/service/nztm.map
 
So I then use a layer definition for OL such as :
 
var topowms = new OpenLayers.Layer.WMS( "Topos",
                         "http://10.64.20.120/cgi-bin/gsswms.exe?",
                          {layers:
['nzislands','nznoaa','nz1mtm','nz250ktm','ci250k','nz50ktm','ci50kcitm'],
transparent: 'true',format: "image/png"},
                          {singleTile: true, isBaseLayer: false,
minResolution: 2000, visibility: false} );
 
regards,

Thanks all for your help, 
I'll have in a near future to implement a fully secured private site
since I'm gonna have to publish VERY sensible data via WMS. I can tell
that this issue scares the IT group. Story to follow... 
But for now, obscurity is sufficient. 

I'm a bit in obscurity myself regardin http_referer...I need to know
more about the mechanic... 
It's not clear what I should do in the mapfile and in my OpenLayers
code? 

I added Daniel's code in Apache conf. 

"Then your WMS requests should refer to the mapfile using "map=MYMAP" 
instead of a full path. If the referrer is not valid, then MYMAP will 
not be set and MapServer will spit out an error."

Do I need to use the MYMAP environment variabble in the mapfile or in
OL code, or both? 

I'm using OpenLayers to create a WMS layer with new
OpenLayers.Layer.WMS(name, url, params, options); 
Instead of the path of the mapfile should I use MYMAP (Environment
variable MYMAP defined in the conf of Apache). If so, Is there some
magic there to get the environment variable value? Should I get it with
some php code? 

Thanks 
Steve

I agree (and I never used the word security). But this may be
sufficient 
in some simple cases.  :)

And for a more complete Access Control solution, everyone is invited to

a presentation of the new GeoPrisma project in a conference near you:
