Thanks guys,

I get that now, in my newness to nginx I was overcomplicating things. My server_name is now doing what I had hoped to achieve.

If you can bear with me for one more question, how do I get the 'client' out of domain.com/client/more/stuff.htm? I want to use the 'client' part of the uri to search a redis key/value pair.

I had success with this code for query strings but couldn't work out how to get the first part of the uri to be my key?

location / {
eval_escalate on;
eval $res {
set_unescape_uri $key $arg_key;
redis2_query get $key;
redis2_pass 127.0.0.1:6379;
}
set_by_lua $path "return require('redis.parser').parse_reply(ngx.arg[1])" $res;
proxy_pass http://app_cluster_1/$path;
proxy_redirect off;
}


Thanks again for all the help!

Chris
