Issue description

I want to pass the nginx's Embedded Variables for upstream applications, below is my proxy-rewrite plugin's config:

{
    "headers": {
        "X-AUTH-UID": "$arg_uid"
    },
    "regex_uri": [
        "^/monitor/(.*)",
        "/$1"
    ]
}

The test url：

curl http://gw.

virtual host options

It may be helpful to not only allow wildcards for HTTP status rules like *, but also 4* .

Would there be any appetite to add a rule that checks for the inclusion of required and optional fields in your API?
