> Reduce default value for aether.connector.http.connectionMaxTtl

>                 Key: MRESOLVER-385
>                 URL: https://issues.apache.org/jira/browse/MRESOLVER-385
>             Project: Maven Resolver
>          Issue Type: Improvement
>            Reporter: Konrad Windszus
>            Assignee: Konrad Windszus
>            Priority: Major
>
> Due to issues with "Connection reset" (outlined in MRESOLVER-383) as first 
> measure the default value of {{aether.connector.http.connectionMaxTtl}} 
> should be reduced from 600 (the default value used in Wagon is 300).
> Some references for connection idle timeouts of common proxies (towards the 
> client):
> * The default idle timeout is 4 minutes = 240 seconds for *Azure 
> Loadbalancers* 
> (https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-tcp-idle-timeout?tabs=tcp-reset-idle-portal)
> * The default idle timeout is for *AWS ALBs* is 60 seconds 
> (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/application-load-balancers.html#connection-idle-timeout)
> * For *Fastly CDN* the default idle timeout for clients is 10 
> seconds(https://www.fastly.com/blog/reusing-backend-connections-increase-performance#keep-alive-timeouts)
> So the current default of 600 seconds seem too high. The questions is to what 
> it should be reduced to given that the connection is currently anyhow 
> revalidated before use after being idle for 2 seconds or longer:
> {quote}
> The code now only checks the connection if the elapsed time since the last 
> use of the connection exceeds the timeout that has been set. The default 
> timeout is set to 2000ms
