Thanks! I thought there were a few people on the list using lighttpd, so 
I was a little surprised to run into this

It seemed like that code was designed to catch the 'no WebDAV' case. 
Since a server's WebDAV support isn't likely to change often, what do 
you think about checking as part of doing test writes?

Or do you want me to throw together a patch with an 'ignore405' config 
option?

BTW, I might make it to LinuxFest up in Bellingham.  If so, I'll say hi.
