[mapserver-users] MapCache and GetLegendGraphic
I successfully added a forwarding rule so mapcache can send a getLegendGraphics request forwarding_rule name=getLegendGraphics param name=REQUEST type=valuesGetLegendGraphic/param param name=SERVICE type=valuesWMS/param http urlhttp:///cgi-wms/mapserv.fcgi?map=wms.map/url /http /forwarding_rule It is working for zoom level 9 - 19If I zoom out at level 8 to 0, the getLegendGraphics request returns this ?xml version='1.0' encoding=ISO-8859-1 standalone=no ? !DOCTYPE ServiceExceptionReport SYSTEM http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd; ServiceExceptionReport version=1.1.1 ServiceException code=LayerNotDefined msWMSGetLegendGraphic(): WMS server error. Mandatory LAYER parameter missing in GetLegendGraphic request. /ServiceException /ServiceExceptionReport I clearly see that LAYER parameter is there. Actually, except for SCALE parameter, the URL is the same as the one for zoom level 9 and + Working url zoom level 9 ...SERVICE=WMSVERSION=1.1.1REQUEST=GetLegendGraphicLAYER=temperature_surfaceSCALE=866685.8312779219FORMAT=image%2Fpng Non Working url zoom level 8 ...SERVICE=WMSVERSION=1.1.1REQUEST=GetLegendGraphicLAYER=temperature_surfaceSCALE=1733371.6625558438FORMAT=image%2Fpng In mapcache config I don't have a restricted_extent for this layer neither min/max zoom parameter I don't know what to look for anymore, any ideas? thank you Steve ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

I used the Nabble search in the MapServer forum, to read how this generic error is thrown for MapServer layers that are in a GROUP. There are tickets and discussions about that. Anyway, not sure if it is related to your issue, but you could also search the archives to see what I mean. http://osgeo-org.1560.x6.nabble.com/MapServer-f4226623.html -jeff -- Jeff McKenna MapServer Consulting and Training Services http://www.gatewaygeomatics.com/ ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] MapCache and GetLegendGraphic
Thanks Jeff but it happens with 3 layers and they are not in a GROUP. If I request the legend on the WMS directly it works. It seems that mapcache is not sending the LAYER parameter in some circumstances...

Re: [mapserver-users] MapCache and GetLegendGraphic
LegendGraphic is not supported. You can however setup a forwarding rule so that those requests get sent to an upstream WMS server. -- thomas On 6 May 2014 22:04, steve.tout...@inspq.qc.ca wrote: Is it possible to make a getLegendGraphic Request via MapCache?
