>Description:
When someone is accessing a /~user/ URL with an older browser that
doesn't include the Host: header in the request, the Alias is ignored
and Apache attempts to look in public_html instead of where the Alias
told it to in srm.conf (verified with ktrace).  If either the Host:
header is present, or /users/user (which is aliased the same way as /~)
is used, it works correctly (I even set ServerName outside of the
virtual host sections, and it made no difference):

Alias /icons/ /var/httpd/icons/
Alias /~ /home/web/
Alias /users/ /home/web/
