[OpenLayers-Users] Example Needed Demonstrating OpenLayers.Request

[Bill Thoen]

Does anyone have a simple example showing how to use OpenLayers.Request 
to move data back and forth between an OL application and a 
PostgreSQL/PostGIS database? I got this to work using zXml library 
calls, but if I can do the same thing from within the OpenLayers 
framework, then I wouldn't need to load that library. Unfortunately, I'm 
still pretty new to AJAX, and the lack of detailed documentation on the 
OpenLayers.Request class puts this out of my reach without some help.

TIA,
