The response of http dav module on mkcol request has a problem. The "Location" header has a '\0' . This will cause some client wait to timeout.

e.g.
Location: http://localhost/path/created\0\r\n

I found in "ngx_http_dav_mkcol_handler" , after remove the tail '/' , it does not reduse the length of the uri.

patch:
