I strongly recommend to use the Apache 2 version(s) as advertised(recommended) by apache.org. Raimund is right, you should use Apache 2.0.42 or newer. Because of the security fixes made by apache.org for the newer versions, I personally use and recommend Apache 2.0.45. Note that since 2.0.42 the internal API of Apache did not change any more, so the webserver module for 2.0.43 from the download area is still the actual one.
All the best
