</font><br>
</div>
<div></div>
<div>
<div>Hi all,</div>
<div><br>
</div>
<div>We are consuming WMS services hosted by ESRI ArcGIS Server 10.0. The server was upgraded to ArcGIS Server 10.2.2 and we no longer can access layer names with spaces.</div>
<div><br>
</div>
<div>This is the server’s capabilities.</div>
<div>http://ndgishub.nd.gov/arcgis/services/All_Elevation/MapServer/WMSServer?request=GetCapabilities&service=WMS</div>
<div><br>
</div>
<div>This is the layer I am using.</div>
<div><br>
</div>
<div>
<div>LAYER</div>

<div>END</div>
</div>
<div><br>
</div>
<div>Mapserver encodes this request as follows. Notice that the layer name, which is ‘Topomap DRG 250k’, is encoded with the spaces becoming the ‘+’ character.</div>
<div><br>
</div>
<div>http://ndgishub.nd.gov/arcgis/services/All_Elevation/MapServer/WMSServer?LAYERS=Topomap+DRG+250k&REQUEST=map&WMTVER=1.0.0&SERVICE=WMS&FORMAT=image/png&STYLES=&HEIGHT=1146&SRS=EPSG:2266&WIDTH=1271&BBOX=1906240.15992838,596656.333359479,2119730.85012732,789150.692893686&TRANSPARENT=TRUE&EXCEPTIONS=INIMAGE</div>
<div><br>
</div>
<div>This returns the error in an image that says “Parameter ‘layers’ contains unacceptable layer names.”</div>
<div><br>
</div>
<div>When I replace the + in the layer name with %20, LAYERS=Topomap+DRG+250k become LAYERS=Topomap%20DRG%20250k and the request becomes the following.</div>
<div><br>
</div>
<div>http://ndgishub.nd.gov/arcgis/services/All_Elevation/MapServer/WMSServer?LAYERS=Topomap%20DRG%20250k&REQUEST=map&WMTVER=1.0.0&SERVICE=WMS&FORMAT=image/png&STYLES=&HEIGHT=1146&SRS=EPSG:2266&WIDTH=1271&BBOX=1906240.15992838,596656.333359479,2119730.85012732,789150.692893686&TRANSPARENT=TRUE&EXCEPTIONS=INIMAGE</div>
<div><br>
</div>
<div>That request works. Obviously, ESRI is no longer decoding + as a space and therefore does not recognize the layer name with spaces. </div>
<div><br>
</div>
<div>Is there any way I can have mapserver encode all characters using percent-encoding, or at least encode spaces as %20 instead of a + character.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>
