apache http rewrite/redirect based on ip

问题

I want to redirect an ip to another view of my website, for example, I want the visitor from ip x to see
www.xxx.com?_DEBUG=1
while all other visitors see the normal www.xxx.com, how would I do this in apache config file, what directives are used?

回答1:

Here is an example of a rewrite configuration to do what you want - put this inside the virtual host for www.xxx.com on your server:

RewriteCond %{REMOTE_ADDR} 1.2.3.4
RewriteCond %{QUERY_STRING} !_DEBUG=1
#RewriteRule ^/(.*)$ /$1?_DEBUG=1 [QSA,R,L]
RewriteRule ^/(.*)$ /$1?_DEBUG=1 [QSA,L]

A couple of notes:

• Change 1.2.3.4 to whatever IP you need
• The second RewriteCond prevents URLs already re-written to include _DEBUG=1 from being re-written again
• There are two versions of the actual RewriteRule; the first version (commented out) actually performs a redirect. Use this if you actually want the HTTP client to submit a second request to the server including the _DEBUG=1 argument. The downside is that if you're combining GET and POST data, this method will not work.
• The second version of the RewriteRule is what I recommend you use...it doesn't perform a redirect. Instead it just appends the _DEBUG=1 parameter to the HTTP request internally in Apache before the request is handled.
