Besides using the old version of ATS, which is not supported, your config acts
slightly oddly. I think it might even be a bug (it doesn’t run the rules in the
order you’d expect, i.e. it matches the second regex first).

The “expected” syntax for this rule is / was e.g.
cond %{SEND_RESPONSE_HDR_HOOK}
cond %{PATH} /(avi|mp3|jpg)$/
rm-header Cache-Control
add-header Cache-Control max-age=3d [L]
cond %{SEND_RESPONSE_HDR_HOOK}
cond %{PATH} /(doc|xls|ppt)$/
rm-header Cache-Control
add-header Cache-Control max-age=1d [L]
(note that you shouldn’t have to use “” around the regexes). I’ll file a bug on
the other issue in a bit, your syntax technically works, but ordering seems
wrong.
