I wish to config .htaccess apply for my domain make it possible for Symlinks making these:

public_html/a/folder1/folder2/folder3/ indicates public_html/b/folder1/folder2/

Plese produce the entire code of these

This can rewrite your URL:

RewriteRule ^b/folder1/folder2/$   a/folder1/folder2/folder3/

if put forth : example.com/b/folder1/folder2/ it teaches you example.coma/folder1/folder2/folder3/

Edit:

RewriteCond %{HTT_HOST}  ^domain\.com$
RewriteRule ^/folder2/folder3/$  http://domain.net/folder1/folder2/
