you just need to activate the GDAL debug by setting to ON the CPL_DEBUG environment variable. after that you will be able to see all the request done to the WFS server. For example, using the command line, with ogrinfo: $ ogrinfo -ro WFS:"http://geohub.jrc.ec.europa.eu/effis/ows"; WFS: http://geohub.jrc.ec.europa.eu/effis/ows?SERVICE=WFS&REQUEST=GetCapabilities&ACCEPTVERSIONS=1.1.0,1.0.0 HTTP: Fetch(http://geohub.jrc.ec.europa.eu/effis/ows?SERVICE=WFS&REQUEST=GetCapabilities&ACCEPTVERSIONS=1.1.0,1.0.0) WFS: GetFeature operation supports hits WFS: Transaction support !
