How to do a redirect correctly?

Question

PHP

The problem is that the html comes in but is not replaced. The address also remains the same. Those. instead of a full redirect, we simply initiate a request.

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) index.php?route=$1 [L,QSA]

redirect function and its call

public function redirect($url) {
        header('Location: ' . $url);
        exit;
    }
redirect('http://' . $_SERVER['HTTP_HOST'] . '/ViewCollection');

Answer 1

At you the request hour not an ajax goes?

Answer 2

Could you describe in more detail what exactly you want to achieve? What does it mean to "replace the old code with the new one"?

Moreover, it looks like this (request - 302 empty response - the browser executes a get request at the address specified in the redirect - it receives the html code).

It was you who described the normal operation of a 301 redirect. This is how it should work.
Maybe you wanted some other redirect ?

Answer 3

Do you have HTTP 302 in response headers?
