Cache invalidation is a process in a computer system whereby entries in a cache are replaced or removed.It can be done explicitly, as part of a cache coherence protocol.If a username is specified, that user is logged out.You must have super user access to be able to log out a user other than yourself.To control the versions of objects that are served from your distribution, you can either invalidate objects or give them versioned file names.If you'll want to update your objects frequently, we recommend that you primarily use object versioning for the following reasons: For more information about object versioning, see Updating Existing Objects Using Versioned Object Names.In addition, you cannot invalidate objects that are served by an RTMP distribution.You can submit a specified number of invalidation paths each month for free.
Invalidation is carried out by changing the application data, which in turn marks the information received by the client as out-of-date.

If you submit more than the allotted number of invalidation paths in a month, you pay a fee for each invalidation path that you submit.
