[QGIS-Developer] QGIS Server does not wait for remote SVG before rendering

[René-Luc Dhont]

Hi devs,

We encountered a strange issue with QGIS Server, a point layer with a 
simple style using a remote SVG.

At the first GetMap request to this layer, QGIS Server rendered an image 
with missing symbol, the ?.

At the second same GetMap Request, QGIS Server rendered an image with 
the remote SVG.

And sometimes the remote SVG is not drawn and replaced by the  ?.

Do you know if the renderer or the styler has a timer to wait for SVG ? 
Is It configurable ? or the context can be configured to wait for svg or 
an error ?

Regards,
René-Luc
