RewriteRule ^(.*)$ /index.php/$1 [L]
2nd
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
I also changed the line in, CI/application/config/config.php
$config['index_page'] = '';
$config['uri_protocol'] = “REQUEST_URI”

Answer 1

This should work
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ CI/index.php/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

Answer 3

Follow the following step:
Change the config file like this:
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';
Use the following .htaccess:
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
Note: .htaccess vary depending on server. Some server (e.g.: Godaddy) need to use the following .htaccess:
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
see here
Use the following code in base_url:
$config['base_url'] = 'http' . ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 's' : '').'://'.$_SERVER['HTTP_HOST'].str_replace('//','/',dirname($_SERVER['SCRIPT_NAME']).'/');
