I think that you could check that the server does not return an exception.

If REQUEST=GetProjectSettings does not return an exception it means that
it's QGIS.


Example:
QGIS:
http://demo.qgis.org/cgi-bin/qgis_mapserv.fcgi?map=/web/demos/south_perth/project.qgs=WMS=GetProjectSettings

Not QGIS:
http://demo.mapserver.org/cgi-bin/mapserv?map=/osgeo/mapserver/msautotest/world/world.map=WMS=GetProjectSettings

Thanks - I'll try it. What do I detect in the response to know it's QGIS
Server? In fact, does someone have a publicly accessible QGIS Server I can
issue that request to?

Thanks

That's not robust, with a rewrite you can easily hide/alter that path.

I suggest you to rely on a WMS getProjectSettings call.

AFAIK that call is unique to QGIS Server.

[Qgis-developer] Detect whether layer is from QGIS Server

[Tom Chadwin]

I need to detect whether a QGIS WMS layer is from QGIS Server, rather than
another WMS server:

https://github.com/tomchadwin/qgis2web/issues/306

What's my best method? Search for "qgis_mapserv" in the layer's URL? 
Something else?
