Apache Virtual Hosts Error

Recently I setup a sub domain using an Apache virtual host.Since then it worked fine and I used it for redirecting purpose.But yesterday I changed the redirect values of the sub domain from config file.Now the config files show that the changes have been done correctly,but the redirection is still not changed when browsing

It still redirects to the old value which was there before changing config.I tried cleaning cache and it didn’t work either…Any help is appreciated !
