I have two url's for the same domain
1) www.testurl.co.za/folder1 2) www.testurl.co.za/folder2
The main website is within www.testurl.co.za/folder1 , if visitors enter www.testurl.co.za/folder2 the website within folder1 should load but the url should still display www.testurl.co.za/folder2. So with other words folder2 needs to point to folder1
Is this possible to achieve using a .htaccess file in folder2? If so how?
