mod_rewrite to keep subdomain in URL

I have this application that I want to support multi languages. I thought the easiest way would be to use sub domains aka

http://fr.domain.com/content

Now I created the sub domain on my server, pointing to the main root and indeed, the above URL is accessible.
The problem now are all my links, which are absolute.
Is there a way with mod_rewrite to catch the language from the URL and than rewrite the links to the same sub domain URL?

So if we are on http://fr.domain.com/content and click the link http://domain.com/link I want the page to load as http://fr.domain.com/link

Is that possible? Cheers!

So you're saying your website has links like <a href="http://domain.com/link"> instead of just <a href="/link">??? Is there some reason your links are coded like that?

Would you be happy with whipping out a text editor and search/replace'ing those hrefs instead of doing something a-typical or excessively complex with URL rewriting?

You probably need some kind of on-the-fly HTML rewriting tool like mod_proxy_html. This tool was specically designed for rewriting the links in pages on the other side of a reverse proxy but it should be possible to use it for generic link rewriting. Specifically the docs say:

Normally, mod_proxy_html will refuse to run when not in a proxy or when the contents are not HTML. This can be overridden (at your own risk) by setting the environment variable PROXY_HTML_FORCE (e.g. with the SetEnv directive).

The module is quite configurable and supports conditional rewriting and regexes so with some tweaking it should do what you want.

You would probably have to check HTTP_REFERER if you want to do this through apache. It might be good to start updating the site so that the links are dynamic in the future...

Something like (I can't really test this currently):

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_HOST} !^[a-z]{2}\.host\.com$ [NC]
RewriteCond %{HTTP_REFERER} ^http://([a-z]{2})\.host.com/.*$ [NC]
RewriteRule (.*) http://%1.host.com/$1 [R,L,QSA]

EDIT: removed a NOT in the 3rd condition

You might have to check some other conditions, but test things out to figure out what works. Plus, if you do other redirects you need a way to maintain the original referrer. In some ways even with the links the way they are, it may be easier to do this through a more dynamic means with php (through session) or something.

I was using these:
