Anyone using Lighttpd + webdav and a PHP handler?

i.e. using PUT and using a .php script as the handler for it? I can successfully PUT a file to /path/to/file-that-doesnt-exist.txt However, when I try to do a PUT to an existing .php script it gives me access denied, most likely due to the fact that a file exists. I don't want it to actually try overwriting the file, and is-readonly = "enable" or "disable" doesn't seem to change this behavior... Just wondering if anyone out there has done this. I did it no problem in nginx using a .php handler and set DAV to readonly - no issues whatsoever...
