Subject last modified header
Date Mon, 10 Jun 2002 22:41:08 GMT


    On the Apache web server, the last modified HTTP header is returned if
    the HTML or SHTML file is executable. If the file has only read
    permission, then no last modified information is returned.

If this is still the case, it is impossible to take advantage of
Solaris' priority_paging if "last modified" header is also wanted.

Can this be changed to send "last modified" header everytime?
