I don't know if this could be possible on apache yet, I've done hefty amount of research before coming here. but:
I have a VirtualHost running at **:80*, ServerName to somedomain.tld. What I want to achieve is if client 10.2.1.4 accesses somedomain.tld, the client will be served content from DocumentRoot /var/www/pages-1/. Then if 10.3.0.* accesses the same somedomain.tld, the client will get content from DocumentRoot /var/www/pages-2/. Is there any way to achieve this currently?
You can do this with a RewriteRule preceded by a RewriteCond that checks the remote_addr (remember using % for the vars, not $:
It won't be possible to change the document root, but you can rewrite the URL based on the client IP, something like...(not tested)...
Although it might be simpler to use an external rewriting program if the number of IP addresses is very large.
