Subject svn commit: r164092 - /httpd/httpd/trunk/server/util.c
Date Thu, 21 Apr 2005 17:30:22 GMT
Author: jim
Date: Thu Apr 21 10:30:21 2005
New Revision: 164092

URL: http://svn.apache.org/viewcvs?rev=164092&view=rev
Log:
Ensure that we always return a FQDN... This is not guaranteed by either
apr_sockaddr_info_get() or apr_getnameinfo(). Also note that under
OS X, apr_getnameinfo() always seems to fail (at least on my
machines) so if we don't specific ServerName at the global setting,
we get a warning.
