Variable substitution and WMS

[John Cole]

Tom,
  We have an asp.net/atlas wrapper that calls out to mapserver via CGI.  I
would like to change that to use WMS.  If I understand correctly, I should
be able to simply add a few more parameters to the WMS request string and
mapserver will use those the same way as a mode=map request and substitute
them into %var% tags?

Thanks,

John

You should be able to use it with OGC:WMS, however a client would
require more intelligence to pass along those variables.  i.e. a vanille
OGC:WMS client would need to be enhanced for this.

Additionally, you can take a look at the Mapscript WxS services
capability through you favourite scripting language, which can now
expose as OGC Web Services (see the MapServer OGC Web Services Workshop
[http://ms-ogc-workshop.maptools.org/] for more info and examples).
