bug: limit-conn

[LY-GO]

Issue description

I had test the plugin of limit-conn.I found the question that the same ip only request the router by five times when conn is 5 and key is remote_addr, and i don't request the router next time.Why so that?

Environment

• apisix version (cmd: apisix version):
• OS:

Minimal test code / Steps to reproduce the issue

Plugin limit-conn Edit
conn=5
rejected_code=503
burst=0
key=remote_addr
default_conn_delay=0

What's the actual result? (including assertion message & call stack if applicable)

same user only visit the router with the config

What's the expected result?

i hope that the plugin only limit concurrency,and different users also continue to request the router when user request the service after first .

What is the difference between different users? The client's IP address or other things? Please confirm this first.

and please provide a mini case which we can reproduce your bug.

one questions:
you had said the request would been allowed when concurrence declines.When i test the plugin of limit-conn,even through i decline the conn,the request still is unsuccess. this is a bug ?

I think you should provide a complete case, we need to know more detailed step information.

Mainly two questions:

1. What is the route data?
2. What is your test method?
