问题
I have an Apache virtual host that looks like this:
<VirtualHost *:80>
ServerName host1.example.com
ServerAlias host2.example.com
DocumentRoot /srv/web/host1.example.com/pub
</VirtualHost>
I have the following file:
/srv/web/host1.example.com/pub/test.php
I am requesting the following URL (notice that I am using the ServerAlias
, not the ServerName
:
http://host2.example.com/test.php
I'd like to have test.php
output the ServerName
variable somehow (host1.example.com
). Is there any way to do that?
回答1:
Apparently, when you access a VirtualHost through the alias, there is no trace of the original
SERVER_NAME
in any of the $_SERVER
variables.
The only idea that comes to mind is setting an environment variable:
SetEnv MY_HOST host1.example.com
this should set the value of $_SERVER["MY_HOST"]
to the correct host name. No guarantees though, I have never tried this in practice.
