#### 3.4.3 Container URLs

IMAIL also uses URLs to refer to containers. The notation used for a container is what you would expect: take a folder URL and drop everything after the rightmost slash. For example, the folder URL

    imap://localhost/inbox/sysadmin/equipment

has the corresponding container URL

    imap://localhost/inbox/sysadmin/

Note that this is different from the URL for the `sysadmin` folder:

    imap://localhost/inbox/sysadmin
