Chai created TS-4748:
------------------------

             Summary: Congestion Control (congestion.config*(max_connection))
                 Key: TS-4748
                 URL: https://issues.apache.org/jira/browse/TS-4748
             Project: Traffic Server
          Issue Type: Test
          Components: Configuration
            Reporter: Chai


Hi,

I have few questions with the congestion control features inside the apache traffic server.

Q1: How to calculate the max_connection? If 2 people request a web page at the same time and the max_connection equal to 1, its that means congested for origin server and who will get the error page?

CASE 2: Maximum Number of Connections
-------------------------------------
TS will temporarily mark a server as congested if a "max_connection" number
to the server is reached. If a new client request comes in and needs a new 
connection to the server, the client will get 503 Retry-After back. 
There is no PRAT on the "max_connection" reached servers.

Q2: According to case 2 inside the congestion control as above, what is the time of "temporarily mark a server as congested"?

Q3: If a HTML page there are more than one 503 "too many users" return back from traffic server, is the server marks as congested and will show the error page?

Thanks.
