How to redirect a regular page to a 404 or 403 page?

Question

Joomla

Hello, please help me to do something like this. How can I make this link on my website http://www.mysite.ru/index.php/videoroliki?page14 redirect to 404 or 403 for example?
Site on joomla 3.

Answer 1

If the page does not exist, then the server's 404 response should occur by default.

Answer 2

Open .htaccess (in root folder) and write this,

ErrorDocument 404 /404.shtml
ErrorDocument 403 /403.shtml
ErrorDocument 503 /503.shtml

Of course, if not, these pages will need to be done.

Answer 3

ErrorDocument 404 /index.php/videoroliki?page14 is for 404 errors
ErrorDocument 403 /index.php/videoroliki?page14 is for 403 errors
