RewriteCond将域重定向到另一个域，除了一个脚本，执行相反的操作

Question

1) in general, I want everything on www.ABC.com to be redirected to www.XYZ.com

2) EXCEPT when it's www.ABC.com/this/123([a-z]+).html ... it must Rewrite (NOT redirect) to ... www.ABC.com/that_script.php?var=123

3) Also EXCEPT: when it's www.XYZ.com/this/123([a-z]+).html ... it must go (redirect) to .... www.ABC.com/this/123([a-z]+).html (so the 2nd rule will apply after that)

EDIT Both domains parked on the same hosting, so sharing the same HTACCESS

EDIT2 Language of the project is PHP

---

I tried various RewriteCond with %{REQUEST_URI} or %{SCRIPT_FILENAME} but it never works, either saying it's an infinite loop or simply don't take the condition at all.

---

EDIT3 In PHP, it would looks like that...

if( FALSE !== strstr($_SERVER['HTTP_HOST'], 'ABC.com') && FALSE !== strstr($_SERVER['SCRIPT_FILENAME'], 'that_script') ) {
    header("Location: http://www.XYZ.com".$_SERVER['REQUEST_URI'],TRUE,301);
}
if( FALSE !== strstr($_SERVER['HTTP_HOST'], 'XYZ.com') && FALSE === strstr($_SERVER['SCRIPT_FILENAME'], 'that_script') ) {
    header("Location: http://www.ABC.com".$_SERVER['REQUEST_URI'],TRUE,301);
}

I want this, but in HTACCESS

Answer 1

Use this code in your .htaccess under DOCUMENT_ROOT:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# Redirect www.xyz.com/this/123([a-z]+).html to www.abc.com/that_script.php?var=123
RewriteCond %{HTTP_HOST} ^(www\.)?xyz\.com$ [NC]
RewriteRule ^this/(123)[a-z]+\.html$ http://www.abc.com/that_script.php?var=$1 [R,L,NC]

# Forward www.abc.com/this/123([a-z]+).html to www.abc.com/that_script.php?var=123
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^this/(123)[a-z]+\.html$ that_script.php?var=$1 [L,QSA,NC]

# Redirect abc.com to www.xyz.com
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^ http://www.xyz.com%{REQUEST_URI} [R,L]

Change all R to R=301 once you have verified that it is all working fine.

Also note that I have used first RewriteRule in a way to avoid 1 extra forward (RewriteRule # 2 above).
