域.301 .htaccess重定向

Question

I have a domain on Namecheap that I set up to redirect to a url on a different site. The problem is now it redirects everything, including paths that do not exist on the new site.

So old url:

domain.tld/bla/bla 

becomes

newdomain.tld/theredirectedurl/bla/bla 

which throws a 404 error.

My question is basically how to .301 all the incoming links from the old site to the new url:

newdomain.tld/theredirectedurl/

I tried setting up a refferer redirect but I think because the site goes thru Sucuri firewall that won't work.

RewriteEngine On 
RewriteCond %{HTTP_REFERER} ^http://olddomain.tld/[OR] 
RewriteCond %{HTTP_REFERER} ^http://www.olddomain.tld/ 
RewriteRule .* http://www.newdomain.tld/products/lines/product/ [R=301,L]

Any help would be appreciated.

Thanks

Close. Use HTTP_HOST so it redirects immediately, referer [sic] wouldn't have any affect on first page view, only resources and subsequent clicks.

RewriteEngine On
RewriteCond %{HTTP_HOST} =olddomain.tld [OR]
RewriteCond %{HTTP_HOST} =www.olddomain.tld
RewriteRule ^ http://www.newdomain.tld/products/lines/product/ [R=301,L]
