webDAV servlet and PUT/MOVE concurrency

[jo...@cexp.com]

Greetings,
	I know that webDAV specifies that a MOVE command will do a copy and
delete, but that takes too long on our target box.  What is the best way to
change the behavior of the servlet so a MOVE does a move?
	Since my remote files are picked up by a scheduled job (runs every
few seconds), it must land completely in the directory all at once.  Up
until now we've been using a custom servlet that writes the file to a temp
directory and the moves it to the final directory.  Now we're looking to use
webDAV to make our software more compatible, but it has to fit this
constraint.
	I was thinking of subclassing the servlet and just changing the MOVE
functionality.  Is there a better way?
Thanks,
Joe

The WebDAV specification says that a MOVE must be equivalent to a COPY 
then a DELETE, not that it must be implemented as such. An 
implementation that actually moves the files directly would be perfectly 
valid. However, slide does not have any way to so such a modification in 
its internal store interfaces - adding it would be possible, but a 
non-trivial amount of work.
