Hi list, Thanks Alessandro. Indeed, I started looking in to the source. It made me wonder: how does a QGIS Server fcgi instance go about varying MAP=... parameters in subsequent requests?
>From source it seems to me that the QgsProject object is retained across the handling of requests (by its fcgi loop). Yet: how about requests coming in that pass different "MAP=" parameters, selecting different .qgs files?

Note that with some performance degradation you can still run the server as plain old CGI. AFAIK there are no documents about the implemementation: follow the source Luke :) Cheers.
