Question:
I know of no client that will automatically refetch a document (if it is the
current on the screen) if the current time surpasses the Expire time specified
for the document. Correct?

Note
This field can also be used for automatic refreshing of dynamic or volatile
data. However, this is completely dependent on the implementation of the client
application to automatically issue a new request when the object has expired.
Object's generated by data-producing processes, or scripts which can be run by
such processes, are often dynamic by nature. Therefore, it is strongly
recommended that responses containing such Objects's contain an Expires header
field.
