Exclusive locking does not set Lock-Header #12
Description
When a lock is taken, a Lock-Token header should be emitted in the response, with the <uuid:urn:[guid]> value.
To resolve this error, add the following line in WebDavLockMethodHandler, line 251:
context.Response.AppendHeader("Lock-Token", "<" + locktoken.ToLockToken() + ">");
This fixes litmus test locks#6.
