Good evening Stephan, I am interested in using your inteproxy tool with QGIS to access WMS via https. However I have installed inteproxy on windows and I fall at the first test. When I enter the following into firefox or IE: http://localhost:64609/inteproxy-demo.intevation.org/cgi-bin/frida-wms?Request=GetMap&Version=1.1.1&service=WMS&layers=strassenall,sehenswuerdigkeiten&format=image/png&width=200&height=200&srs=epsg:31467&bbox=3427000,5787590,3444000,5800880 I get this error: Error response Error code 502. Message: Bad Gateway. Error code explanation: 502 = Invalid responses from another server/proxy.. Do you have any ideas what may cause this. Have I ommitted to do some key configeration for instance? Thankyou in advance for your help, I look forward to hearing a solution and using your potentially very useful tool.
