htaccess rewrite rule for specific domain

Question

So I have this rule that's working perfectly:

RewriteRule ^images_designs/([^.]+)-d00([^/]+)\.png$ /image_design_watermark.php?design=$2 [L,QSA,NC]

Now I would just add an additional "language" variable related to the domain the htaccess is used on

I have tried this but it's not working:

RewriteCond %{HTTP_HOST} ^(ni-dieu-ni-maitre|blablabla)\.com$ [NC] 
RewriteRule images_designs/([^.]+)-d00([^/]+)\.png$ /image_design_watermark.php?design=$2&language=fr [L,QSA,NC]

RewriteCond %{HTTP_HOST} ^(no-gods-no-masters|ni-dios-ni-amo)\.com$ [NC]
RewriteRule images_designs/([^.]+)-d00([^/]+)\.png$ /image_design_watermark.php?design=$2&language=en [L,QSA,NC]

Answer 1

The %{HTTP_HOST} includes subdomains so you should add the www into that.

RewriteCond %{HTTP_HOST} ^(?:www\.)?(ni-dieu-ni-maitre|blablabla)\.com$ [NC]

and

RewriteCond %{HTTP_HOST} ^(?:www\.)?(no-gods-no-masters|ni-dios-ni-amo)\.com$ [NC]

or you could make it looser and take off the starting anchor, ^ I'd go this route though.
