[Duplicate] Base _url and virtual hosts

i have both codeigniter 3.0.1 and 3.0.4 , when i setup virtual hosts in xampp for both and echo the base_url i get 127.0.0.1 for codeingniter 3.0.4 instead of the actual virtual host name, while codeigniter 3.0.1 echos the correct virtual host name.

This has been addressed a number of times in the forum already.
It is a result of a change in version 3.0.3 ... http://www.codeigniter.com/user_guide/ch...sion-3-0-3
