SSI and expires header

[Markus Jelsma]

We also tried using the Nginx sub module but this module as well strips away any Last-Modified header, even when we force the Last-Modified header with headers more using a perl_set subroutine returning the proper date.

Any suggestions are very welcome :)

We know SSI removes the Expires header set by the standard headers module so we wrote a small perl_set sub that returns a proper HTTP expires date in the future which we set using the headers_more module. Testing via curl -i returns and checking in the browser confirms the Expires header is set correctly. We also output a Cache-Control header.
