[Qgis-developer] QGIS Mapserver GetMap VERSION parameter

[Marco Hugentobler]

Hi Pedro

QGIS server is intentionally more tolerant than the standard. Because it 
officially supports version 1.3. However, most clients use 1.1.1 or even a 
different version. Therefore, QGIS server replies to all versions (with a few 
slight changes if 1.1.1). In general, this works well. 

With a strict version check, most clients would just see a 'version not 
supported' exception.

Regards,
Marco
