Hello,

http://nginx.org/en/docs/http/ngx_http_map_module.html
Before version 0.9.0 only a single variable could be specified in the first
parameter.

map $arg_option$arg_view$arg_id$arg_itemid $redirect_uri {
com_contentarticle40106 /blahblah/page1;
com_contentarticle164139 /blahblah/page2;
}

....

location / {
if ($redirect_uri) {
return 301 $scheme://$host$redirect_uri;
}
}

It's also order-independent. And this is an Orthodox way :)
