Custom HTTP verbs get converted to GET requests upon redirect
As reported in opentodolist#437 (closed) and QTBUG-92909, when using a custom HTTP verb and the request gets forwarded, the verb in the final request towards the server is changed to GET
. This causes the WebDAV jobs to fail, as the result will most likely be the folder list as produced by some servers when visiting the same URL in the browser.
We should handle this by doing own redirect handling in WebDV requests that use custom verbs.
