CodeIgniter remove index.php from href - apache

Question

In a CodeIgniter App
this link works
link
while this one doesn't
link
What's wrong with configuration? What has to be changed in order links work without "index.php/" at the beginning?
This is done without success:
1) added to application/routes.php
$route['(:any)'] = 'controller';
2) added to application/.htaccess
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
<Files "index.php">
AcceptPathInfo On
</Files>
3) uncommented in etc/apache2/httpd.conf
LoadModule rewrite_module libexec/apache2/mod_rewrite.so
LoadModule php5_module libexec/apache2/libphp5.so

Answer 1

First of all you should blank the
$config['index_page'] = '';
in config
config.php
Then write the following code in .htaccess placed in your project's main directory.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>

Answer 2

Use this in your .htaccess to remove the index.php from the url
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php?/$0 [PT,L]
Your link should be
link
Config.php should be
$config['index_page'] = '';
The rewrite_module should be activated in apache
