Disable URL Rewrite for subdomain - .htaccess

Question

I'm using Apache web server ( use .htaccess to handle URL Rewrite ).
the main domain ( e.g. example.com ) is managed by URL Rewrite generated by WordPress. The URL Rewrite applies for whole domain , including sub-domains.
I have a new subdomain called http://static.example.com, which acts a URL forward to another external URL, e.g. forward to http://www.google.com. That's :
http://static.example.com/style.css will forward to http://www.google.com/css/some_path/style.css
However, the URL Rewrite blocks it, and reports file not found, as it cannot find the /css/style.css in local server. My question is: How to disable URL Rewrite for subdomain ?
The current .htaccess is as follow:
RewriteEngine on
AddType application/rss+xml rss
AddType application/x-java-jnlp-file jnlp
Options All -Indexes
RewriteCond %{HTTP_HOST} ^www.example.com$
RewriteRule ^/?$ "http\:\/\/example\.com" [R=301,L]

RewriteCond %{HTTP_HOST} ^static\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.static\.example\.com$
RewriteRule ^/?$ "https\:\/\/google\.com\/css\/some_path\/" [R=301,L]
Note: note that the forwarding is actually included above.
p.s. all URLs are fake.

Answer 1

replace
RewriteCond %{HTTP_HOST} ^static\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.static\.example\.com$
RewriteRule ^/?$ "https\:\/\/google\.com\/css\/some_path\/" [R=301,L]
with
RewriteCond %{HTTP_HOST} ^(www\.)?static\.example\.com$
RewriteRule ^(.*)$ https://google.com/css/some_path/$1 [R=301,L]
the whole htaccess would be: (adjusted)
RewriteEngine on
AddType application/rss+xml rss
AddType application/x-java-jnlp-file jnlp
