Re: How to do a MoveMethod with locks

I can not get this to work without adding the url to the If header, the 
server always responds with a 424 error. Experimenting with cadaver in
debug mode, i found that it likes the tagged version. I've also 
discovered that in order to do the move when both the source and the 
destination are locked, the If: header needs both lock tokens provided 
in the tagged version. Unfortunately the way that the slide code is 
organized, there seems to be no easy way to augment this header for the 
destination.

The requirement for the tagged version of the header maybe a bug in 
mod_dav/mod_svn I don't know.
