I believe in that thread, Torsten was suggesting 3 different SSI
techniques to get the Last-Modified header out.  If this one doesn't work,
maybe try the other two, or try them in combination.  I don't know if
any of these are specific to particular versions of Apache or other web
servers, so you should probably look at the documentation for the server
you're using.  Also, I believe we had concluded in that thread that any
SSI tag intended to generate an HTTP header MUST be at the very start
of the document, before any HTML that will be output.

As Geoff suggested, some verbose output from htdig may be helpful.

All the XBitHack does is enable SSI on .html files that have the execute
bit turned on, treating them as .shtml files.  If you're needing to use
SSI tags to get the Last-Modified header to be output, presumably it's
because the files are already server-parsed, so I don't see what the
XBitHack would get you.  If the files aren't server parsed, you should
be getting the header based on the "mtime" of the file.  If the files
are server parsed, but not SSI, then it must be something else like ASP,
JSP, PHP, or some other pre-processor, so you'd need to use whatever
trick that pre-processor allows for getting the header out.
