[Qgis-user] QGIS Server: Cascading WMS possible?

[Andreas Neumann]

 Hi Albin,

 Yes - cascading WMS are supported by QGIS server. I use this quite 
 extensively.

 If it fails on your server one would have to investigate - could be any 
 networking or proxy issues or maybe the server is a different QGIS 
 version than QGIS Desktop. From QGIS 1.8 to master there have been 
 changes in the raster provider. Projects created in QGIS Desktop version 
 1.8 do not necessarily work in QGIS master on the server. It is 
 advisable to use the same version on the server and the Desktop creating 
 the files. This is normally not a big issues, but with the raster 
 provider changes I experienced this problem.
