Apache Configuration Question

make codeigniter guess $baseurl the correct way

On my server i'm using nginx on port

and apache on port
as an internal proxy to nginx.

And i have multiple domains

When i leave the
empty in the config code igniter tries to guess the right base url , it shows that the base url is
instead of

When i set it manually:


It doesn't work when i open the other domains like
for example because the
is still on the
domain .

Is there any way to make code igniter smarter guessing the right


Thanks Charlotte for the tip.

After some search on the HTTP_HOST server variable i discovered that apache is passing the HTTP_HOST to nginx as localhost:8081.

I use reverse proxy in apache to make the proxy behavior:

ProxyPass / http://localhost:8081/ ProxyPassReverse / http://localhost:8081/

I searched the Documentation of apache and found a directive called ProxyPreserveHost

When enabled, this option will pass the Host: line from the incoming request to the proxied host, instead of the hostname specified in the ProxyPass line.

i enabled it by adding this line:

ProxyPreserveHost On

And it worked , now codeigniter can read HTTP_HOST right and make the $base_url right.
