This update for the Apache Web Server introduces directives to control two protocol options:
* HttpContentLengthHeadZero: Allow responses to HEAD request with
Content-Length of 0
* HttpExpectStrict: Allow the administrator to control whether clients
must send '100-continue'
MODULEMAGICNUMBER_MINOR has been increased to 24, as this change is not forward-compatible. Modules built against this release might not work correctly with older releases of the Apache Web Server.
