Nginx dynamic proxy redirection

Question

I was hoping to achieve something like this:

location = / {
    if ($args ~ "^url=(.+)") { #gets the "url" get parameter
        set $key1 $1;
        proxy_pass $key1; #use the parameter as proxy address
    }
}

Is this even possible ?

Answer 1

location / {
    proxy_pass http://backend$arg_url;
}
