[PATCH 13/14] qemuBlockGetBackingStoreString: Properly handle 'http/s' with cookies and others

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Format cookies into the backing store string without encryption as they
will not be visible on the command line when formatting a 'target' only
string. In cases when cookies or other options are used we must use the
JSON format rather than pure URI.

Add tests to validate the scenario.
