Blog subdomain not redirecting

[MarkWill]

Yep, totally agree with the thinking and prefer that approach. I researched the non-www (blank subdomain) solution a while back and the rewrite rule I used was suggested in a number of places. But your suggest seems much more robust, providing there's no gotcha (I know of none).

I implemented this and it seems to be working (after a bit of a detour because of caching :)). So, I think I am good and will monitor.

A big thanks to you and Travis. I very much appreciate the prompt responses.

I'm hesitant to say; "Do X." because I'm not really sure what will happen - with the redirect plugin in the mix. I imagine a lot, if not all of the subdomain folders and pages have already been redirected via the plugin. So I imagine the path of least disaster at the moment is just redirecting the subdomain (sub.domain.com) to the main domain (www.domain.com) alone.

I could be totally wrong, but this one is weird.

Test out the rule and then push live. Here is the code to redirect just the subdomain to just the www domain:

RewriteCond %{HTTP_HOST} ^blog.domain.com$ [NC]
RewriteCond %{REQUEST_URI} ^/?$
RewriteRule .* http://www.domain.com [R=301,L]

Double check it, triple check it and then push live. Keep a very close eye on it. I really hope we don't end up with a loop.

Take a copy of the htaccess file, if something goes wrong, then you can always go back

Looks like that, or some approximation thereof has you sorted. I would just like to add that you should keep an eye on Webmaster Tools.

So far so good - every URL I try to my site is now redirected to the www subdomain and, to date, I am unaware of any side effects. I will keep monitoring but all looks good at this point.

Thanks again to everyone who helped with this.
