+ *    Revision 1.47  2008/03/26 18:07:07  fabiankeil
+ *    Add hostname directive. Closes PR#1918189.
+ *
+ *    Revision 1.46  2008/03/21 11:13:57  fabiankeil
+ *    Only gather host information if it's actually needed.
+ *    Also move the code out of accept_connection() so it's less likely
+ *    to delay other incoming connections if the host is misconfigured.
+ *
  *    Revision 1.45  2007/09/30 16:59:22  fabiankeil
  *    Set the maximum listen() backlog to 128. Apparently SOMAXCONN is
  *    neither high enough, nor a hard limit on mingw32. Again for BR#1795281.
