   You can try the traffic-split plug-in. Here is an example of configuration:
   
   ```shell
   curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: 
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

           "traffic-split": {
               "rules": [
                   {
                       "match": [

                               "vars": [
                                   ["http_id","==","1"]
                               ]
                           }
                       ],
                       "weighted_upstreams": [

                       ]
                   },
                   {

               }
       }
   }'
   ```
   
   However, it may not take effect in APISIX 2.5. You can try it in versions 
before 2.5.
