On the Apache mirrors there are no Windows binaries for Apache 2.2.23 available:
http://apache.proserve.nl//httpd/binaries/win32/
there are binaries for 2.2.22 (and even for netware 2.2.23!) - is
there a reason behind this?
The binaries are not "official", they are built by volunteers who have commit access to the project.
Because the person/people who used to do the build are no longer doing it, there is no build.
This has been an ongoing discussion for months. If and when another committer volunteers to do it, binaries might be included on the mirror.
Until then, just use the Apache Lounge builds.
