what's the point to HEAD the parent folder before uploading

[tbswork1]

The check() function is called before uploading file. The RFC quoted is meant to get index.html in that folder with GET or HEAD or return 404. In webdav, you check the existence of the folder with PROPFIND not GET or HEAD. This causes the upload failed with some webdav servers that have no idea what you want with GET/HEAD on a folder.
