htaccess - moving blog to subdomain

Question

i have a blog, and im moving it to a subdomain. since the URL sintaxis won't be the same, i just want to redirect all url requests that are inside /posts/ to the new subdomain:

from

domain.com/posts/xxxxx

to

blog.domain.com

this is what i have so far, but it still has to filter only the requests that are inside /posts/

RewriteCond %{HTTP_HOST} ^domain.com
RewriteRule (.*) http://blog.domain.com/ [R=301,L]

Answer 1

You're almost there. You just need to modify it so that your regular expression in the RewriteRule only matches stuff inside /posts/ as below:

RewriteCond %{HTTP_HOST} ^domain.com
RewriteRule ^posts/(.*) http://blog.domain.com/ [R=301,L]

Answer 2

The directives:

RewriteCond %{HTTP_HOST} ^domain.com
RewrietRule ^posts/(.*) http://blog.domain.com/ [R=301,L]

... should work.
