Generating “Expires” Headers

The optional mod_expir es module supports the generation of

Expires headers, which inform clients, including proxies, how

long the document contents remain valid and thus how long

they may be cached. Expiration dates are given as intervals

from either the time of the access or the time the file was last

modified, and can be specified as either the letter “

A” (for time

of access) or “

M” (for last modified time) followed by a num-

ber of seconds, or in the format:

base [plus] number period-type...

base may be access or now for time of access, or modifica-

tion for the last-modified time of the file. Valid period types

are years, months, weeks, days, hours, minutes, and seconds.
