Redirect another view using htaccess

Hi all,

I want to access a link

http://localhost/controller/function/product_id -->  view 
to
http://localhost/same_controller/same_fu...oduct_name --> same view open.

Using Htaccess.

Why .htaccess? Just setup a route to do it.

What did you Try? What did you Get? What did you Expect?

Create file in your Codeigniter folder then save as ".htaccess" 
then paste this...

RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ ./index.php/$1 [L]

@rupamhazra: why?
