When making a GetCapabilities request from ArcGis Desktop, how does it get the information needed for making the GetMap request and how is the GetMap request handled by their "sample server"?
For example (taken from their own resource center http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//005300000046000000):
If I use their own sample server and make the following GetCapabilities request: http://sampleserver1.arcgisonline.com/ArcGIS/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer?version=1.3.0&request=GetCapabilities&service=WMS
But how does it get the information needed for making the following GetMap request?: http:/sampleserver1.arcgisonline.com/ArcGIS/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer?version=1.3.0&request=GetMap&CRS=CRS:84&bbox=-178.217598,18.924782,-66.969271,71.406235&width=760&height=360&layers=0&styles=default&format=image/png
Is it only taken from the GetCapabilities response XML or am I missing something here? It's difficult for me to understand how ArcGis Desktop creates the GetMap request and receives the images when I'm only inputting the GetCapabilities request. Is there some documentation I'm missing somewhere? And is there some kind of guideline as to how their "sample server" might be handling the incoming requests?
