Subject Re: [users@httpd] IP based redirect with mod_rewrite
Date Thu, 06 May 2010 01:27:11 GMT
I wonder why the %{REMOTE_ADDR} approach is failing? Are you getting a wrong
REMOTE_ADDR or your rule is not working? Can you please post your rewrite
rule for that case and appropriate rewrite logs with RewriteLogLevel set as
high as possible for debugging?

You can also try to combine SetEnvIf and mod_rewrite for Remote_Addr
parameter but if the above try is failing this one should be failing too
since practically both are checking the same variable.
