$ sudo yum install -y davfs2

Run "mount -t davfs".

$ sudo mount -t davfs https://localhost/webdav /mnt

/sbin/mount.davfs: the server certificate does not match the server name
/sbin/mount.davfs: the server certificate is not trusted
  issuer:      SomeOrganizationalUnit, SomeOrganization, SomeCity, SomeState, --
  subject:     SomeOrganizationalUnit, SomeOrganization, SomeCity, SomeState, --
  identity:    centos-7
  fingerprint: 59:a8:d0:88:aa:e5:dc:47:21:32:4a:63:00:ce:45:68:84:03:86:73
You only should accept this certificate, if you can
verify the fingerprint! The server might be faked
or there might be a man-in-the-middle-attack.

/sbin/mount.davfs: Warning: can't write entry into mtab, but will mount the file system anyway

Write file via WebDAV.

$ echo hello | sudo tee /mnt/hello.txt

For updating written file immediately, unmount /mnt.

$ sudo umount /mnt

Written file can be read in /var/www/webdav.

$ sudo cat /var/www/webdav/hello.txt
