Returns 1 if the epoch is greater than the modified date check.
=head3 epoch
The date that the requested content was last modified in epoch format.
=head3 maxCacheTimeout
A modifier to the epoch, that allows us to set a maximum timeout where content will appear to
have changed and a new page request will be allowed to be processed.
