bug: apisix can't parse cookie

[caihonghaoCYF]

Current Behavior

When I use the trafficsplit plugin to split traffic, when my front-end sends a cookie with the value "OnlyHttp;orderNo=F30", it cannot match the normal F30 upstream. When I debugged, I found that apisix parsed this cookie into the key OnlyHttp;orderNo, but the key should actually be orderNo.

Expected Behavior

No response

Error Logs

No response

Steps to Reproduce

1. craete route
   {
   "update_time": 1732544554,
   "create_time": 1732539917,
   "hosts": [
   "a.test.com"
   ],
   "upstream_id": "734215018329804800",
   "priority": 1,
   "uri": "/e",
   "status": 1,
   "plugins": {
   "client-control": {
   "max_body_size": 4194304
   },
   "traffic-split": {
   "rules": [
   {
   "match": [
   {
   "vars": [
   [
   "cookie_orderNo",
   "==",
   "F30"
   ]
   ]
   }
   ],
   "weighted_upstreams": [
   {
   "weight": 1,
   "upstream_id": "734068621429313536"
   }
   ]
   }
   ]
   }
   },
   "id": "734215018329804800"
   }

2. Send with cookie "HttpOnly;orderNo=F30"

Environment

• APISIX version 3.1.0

HttpOnly should not appear in the Cookie request header sent by the client.
Instead, it belongs in the Set-Cookie response header.
In the Cookie request header, only the actual key-value pairs should be included.
