I would like to achieve this with Apache:

If a client with an IP defined in whitelist.txt tries to access http://site1.com, I want to reverse proxy that to http://site2.com.

If the client IP is not in that list, I just want normal flow to occur and the index.html in htdocs to be served.

I was thinking of doing something along these lines, but I am not sure if that makes sense:

Code:

    RewriteMap iplist "txt:/usr/local/apache2/conf/wl.txt"
    RewriteCond "${iplist:%REMOTE_ADDR}" [ I AM NOT SURE ON THE SYNTAX HERE ]
    RewriteRule "^/(.*)" "http://site2.com/$1" [P]
    ProxyPassReverse / http://site2.com/


If the above, or a version of it works, will the normal index.html be served if an IP is not in the list? Is there a better way to achieve this?

Thanks!

I think it works, it is like the black list example from https://httpd.apache.org/docs/trunk/rewrite/access.html#host-deny

Wouldn't is be easier just to deny the access for all others?
