The mod_expires Apache module adds functionality to Apache that allows you to define the length time before a client will consider data out of date.

This module allows you to define one or both of the following values:

  • The max-age field of the Cache-Control header.
  • The Expires header.


Use this module if you wish to define when a web browser or server will consider your server's data out of date. After you install the module, you must define the max-age value or the Expires header in either .htaccess files or in your Apache configuration files.

For more information how to customize your Apache configuration, read our Advanced Apache Configuration documentation.
