Hi, For a controlled test you should have a way to make the server side to fail when you want so. I am not sure if simply unplugging you network connector would make GDAL to repeat the requests. Installing your local WMS server and stopping it while GDAL is working could be another possibility. Developers probably have better hints for testing.

Am I using these variables correctly, or is there another way to do it?
