HttpCoreContext.HTTP_TARGET_HOST equivalent in hc 5

[Francisco A. Lozano]

Hi,

I'm trying to port a tweaked ConnectionKeepAliveStrategy which applies a
custom behaviour depending on the target host.

With 4.5.x I followed the example in:
https://hc.apache.org/httpcomponents-client-4.5.x/current/tutorial/html/connmgmt.html

and obtained the target host with

    HttpHost target = (HttpHost)
context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);

but this constant is not available anymore in the HttpCoreContext.

What is the right way to obtain the target host from the HttpContext when
moving to http client 5? I was looking at CONNECTION_ENDPOINT and the
remoteAddress of EndpointDetails, but it's not equivalent to a target
hostname.
