Heya,

To achieve the redirects you want using .htaccess, you’ll need to use mod_rewrite rules. Here’s how you can set up the redirects:

1. Redirect www.domain.com/blog/* to www.domain2.com/*:

   This rule will redirect any request that starts with /blog/ to the corresponding path on www.domain2.com.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com$ [NC]
RewriteRule ^blog/(.*)$ https://www.domain2.com/$1 [L,R=301]

2. Redirect www.domain.com/blog/ir/* to www.domain2.com/ir/*:

This rule is specific to URLs that start with /blog/ir/ and will redirect them to the corresponding path on www.domain2.com/ir/.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com$ [NC]
RewriteRule ^blog/ir/(.*)$ https://www.domain2.com/ir/$1 [L,R=301]
