RewriteCond %{HTTP_HOST} ^(?:(?:foo|bar|this)\.com|that\.net)$ [NC]
RewriteRule .? http://foobar.com [R=301,L]

That's not quite working as I want but I think that's my fault for trying ask a too generic question.

What I was looking for was...

www.foo.net
www.foo.org

...to go to...

www.foo.com

So I tried to learn from your code and did this...

RewriteCond %{HTTP_HOST} ^www\.foo\.(?:net|org)$ [NC]
RewriteRule .? http://www.foo.com/ [R=301,L]

...and that seems to work for me.

For my future benefit, and anyone else trying to learn rather than rely on the good services of Anton, what that code is saying is...

Anything starting www.foo. and ending either net or org redirect permanently to www.foo.com

Anton, do you agree with my code and my interpretation of what's going on?

Yes, sure, you are absolutely correct!

What if I want fu.net and bar.com to redirect to fubar.com, but not fu.com or bar.net?

Should add that I have a list of 50 domains I need to redirect to a single domain and was hoping there was an easy way.

You may consider using map files. You may have pairs like:
fu.net fubar.com
bar.com fubar.com
etc.

And use the following config:

RewriteBase /
RewriteMap mapfile txt:mapfile.txt
RewriteMap lower int:tolower
RewriteCond %{HTTP_HOST} (.*)
RewriteCond ${mapfile:${lower:%1}|NOT_FOUND} !NOT_FOUND
RewriteRule .? http://${mapfile:%1} [R=301,L]

Nice. Will try that.

Will it work together with other rules I already have? Like adding www.

Sure it will work with other rules, but then consider adding www part to map files records (if you are adding www prior to map file rules
execution).
