Hello,
there is a short explanation about virtual hosts in Apache ...
https://wiki.centos.org/TipsAndTricks/ApacheVhostDefault
the `hostname` gives a different donmain name than what should be hosted ...
e.g. `hostname` is host.example.org and the domain to be hosted is
example.com, so I did this:
<VirtualHost 1.2.3.4:80>
ServerName host.example.org
DocumentRoot /var/www/default
</VirtualHost>
# used to get let's encrypt for the mail server
<VirtualHost 1.2.3.4:80>
ServerName mail.example.org
ServerAlias smtp.example.org
DocumentRoot /var/www/mail
</VirtualHost>
<VirtualHost 1.2.3.4:80>
ServerName www.example.com
DocumentRoot /var/www/domain
</VirtualHost>
<VirtualHost 1.2.3.4:80>
ServerAlias *.example.com
DocumentRoot /var/www/catchall
</VirtualHost>
the DocumentRoot directories are empty,
only in /var/www/default I have a PHP script: host.php
<?php
header( "Content-type: text/plain" );
printf( "Host: '%s'\n", $_SERVER['HTTP_HOST'] );
?>
now the strange behavior;
http://mail.example.org/ <-- works
http://smtp.example.org/ <-- doen't work
http://smtp.example.org/host.php <-- gives the HTTP_HOST (PHP-script),
but why?
http://www.example.com/ <-- works
http://hello.example.com/ <-- doesn't work
http://hello.example.com/host.php <-- gives the HTTP_HOST (PHP-script),
but why?
doesn't work does mean, that access/errors are logged in a logfile of a
wrong virtual host ...
where is my mistake?
is it problematic, if some virtual hosts have different IPv6 addresses but
the same IPv4 address?
Thanks,
Walter
