Subject Re: Locking
Date Wed, 22 Sep 2010 11:51:48 GMT
Hello Jan,

indeed there's always a few PROPFIND (usually starting at / ) to find
out about the DAV capabilities of the server (I guess, I didn't
confirm this, but seen all DAV clients do the same thing), and then
the 'real' requests are performed (LOCK, PUT, UNLOCK)

Even if it would make perfect sense to do the LOCK 1st and then the
GET, when opening a file, I think it's more conservative to do the GET
first, and only do the LOCK if the file could be gotten fine (GET
succeeded).

Maybe the LOCK, GET, UNLOCK sequence you are seeing is because there's
some network (or other) problem when performing the GET and the file
cannot be properly retreived?

Food for thought. Good luck!
