Version 2.2.6 of Apache

Release Notes: This version of Apache is principally a bug and security fix release. mod_proxy now prevents reading past the end of a buffer when parsing date-related headers. mod_cache now prevents a segmentation fault if attributes are listed in a Cache-Control header without any value. The prefork, worker, and event MPMs now ensure that the parent process cannot be forced to kill processes outside its process group. A possible XSS attack against a site with a public server-status page and ExtendedStatus enabled was fixed. mod_mem_cache now copies headers into longer lived storage.
