title: codeIgniter base url issue
body: <p>Hi i am new in codeigniter, having trouble with link formation. In my page i have link to another page same to <code>&lt;a href = "&lt;?php base_url('feed');?&gt;"&gt;&lt;li&gt;Feed Page&lt;/li&gt;&lt;/a&gt;</code>
  here feed is one of my controller . But the link is showing to me as            <code>http://localhost/BusinessPad/localhost/BusinessPad/feed</code>    ---that  actually doesn't exists. Can't understand how this happen. I have make $config['index_page'] = ''; and add a .htaccess file.</p>
