将特定页面重定向到另一个页面和域

Question

I have a website script that installed on the server and pointed to several domains. Sometimes I need to redirect a specific page to another site and for now, I use Cloudflare feature to redirect the page but there limit for a free plan user. So, I want to know how to redirect the specific page on a specific domain using .htaccess, PHP, or etc?

For example, I have content /blabla on first.com and second.com , Then I want to redirect a page first.com/blabla to third.com/target but not on second.com/blabla , both of domain have the same IP and content is in the same folder.

Thanks

Answer 1

Redirect in php:

<?php header('Location: '. $newURL); ?>

Redirect in javascript:

<script>window.location.href = "newurlhere";</script>

Answer 2

This should work for you.

RewriteEngine on


RewriteCond %{HTTP_HOST} ^(www\.)?first\.com$ [NC]
RewriteRule ^/?blabla http://third.com/something [L,R]
