ESRI Enhanced Web Map Proxy, proxy that helps with improving the web printing.
The proxy allows for the changing out tile map services to dynamic map services so that the user can increase the resolution that the map is produced higher than what the tile services have been created for.
It can also allow if coded at the client end, extra scales that are not possible under the tile services.
For Substituting tile services for dynamis ones .... use these xml tags
i.e.
tile service
url="http://arcgis.ecan.govt.nz/ArcGIS/rest/services/Imagery/MapServer"
dynamic one to change out to
alternate="http://arcgis.ecan.govt.nz/arcgis/rest/services/Dynamic/Imagery_Latest/MapServer"
``
<!-- Imagery Service-->
<substituteUrl url="http://arcgis.ecan.govt.nz/ArcGIS/rest/services/Imagery/MapServer"
alternate="http://arcgis.ecan.govt.nz/arcgis/rest/services/Dynamic/Imagery_Latest/MapServer"></substituteUrl>
For sending maps to esri printing service with scales other than tile scales you need to inject a few more variables.
i.e. tiledLayers
tiledLayers:[{"url":"http://arcgis.ecan.govt.nz/ArcGIS/rest/services/Public/No_Background/MapServer","id":"Basic","title":"Basic"},{"url":"http://arcgis.ecan.govt.nz/ArcGIS/rest/services/Public/Region_Base/MapServer","id":"Regional Base","title":"Regional Base"},{"url":"http://arcgis.ecan.govt.nz/ArcGIS/rest/services/Public/Region_Base_Labels/MapServer","id":"Regional Base Labels","title":"Regional Base Labels"}]
Below is as per normal POST to Webmap printing service. (addtional parameter is above )
