   hi @jamesislebron , take a look at https://github.com/apache/apisix/blob/master/docs/en/latest/router-radixtree.md#how-to-filter-route-by-nginx-builtin-variable.
   
   here is an simple example:
   ```
   $ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
   {
       "uri": "/index.html",
       "vars": [
           ["http_version", "==", "1.0.0"]
       ],
       "upstream": {
           "type": "roundrobin",
           "nodes": {
               "39.97.63.215:80": 1
           }
       }
   }'
   ```
   
   This route will require the request header `version` equal `1.0.0`.
