Many corporations require that all software used have a commercial support structure available to cope with worst-case scenarios. Typically many open-source applications in use today don't have support available from the core development team, and the ubiquitous Apache HTTPd web server is no different. To the rescue is the company Covalent who can provide not only support for several of the Apache products but also make a customized bundle available of Apache HTTPd, Tomcat and several other applications. Obviously this support is not going to be free, but if you need it they're worth giving at try.
