[mapserver-users] How to integrate Openlayers + MapScript C# + Postgis

[Marco Araujo]

Thanks Stephen,
I believe that it would not to use CGI for I will apply different filters on the data map. For example, my User can filter the map by rivers, companies, names of residents, etc..In some cases, such as streets, will display the map with the selected street.
I believe that it is not possible to do in CGI. So understand that I need to use mapscript.
How can I get an example to simulate a WMS service to receive the parameters of openlayers? Well I'll need to get these parameters in the database (using 'select from where params') in order to assemble the map and return to openlayers.

Sincerely,Marco
