When mod_pagespeed fetches an origin resource, the caching headers may be in 
one of several states:

1. Expiration not set
2. Expiration set in the far distant past, which might mean that the site admin 
intended to have the header be uncacheable
3. Expiration set in the past, but within the last few years, which might mean 
that the site-admin has forgotten to manually freshen the headers.
4. Expiration set in the future.


For case #3, mod_pagespeed might benefit the site admin by issuing a warning in 
the Apache error log.

Summary was: Log resources that have expired in the past when they are fetched

This issue has not yet been fully addressed, although +debug now results in 
more data about flushes.

Also of interest for the 'debug' filter, indicating amount of time spent 
fetching, caching, & rewriting.

Is this one of the ones we just handled in the debug fixit?

Huh.  My CL is supposed to address this sort of thing, but I don't give
much detail about the headers when something's expired.  That'd be worth a
look, it shouldn't be that hard.
