Joseph Walton commented on HTTPCLIENT-1575:
-------------------------------------------
I think using those standard default ports would be a good approach and cause
fewer surprises. At worst, someone using {{SchemePortResolver}} to point
{{http:}} to something other than 80 would have exactly the same failure mode
as now (no matching because 80, as opposed to no matching because -1).

> {{PoolingHttpClientConnectionManager.setMaxPerRoute}} can be called with an
> {{HttpRoute}} constructed from an {{HttpHost}} using -1 to indicate the
> default port:
> {noformat}
> connectionManager.setMaxPerRoute(new HttpRoute(new HttpHost("localhost", -1,
> "http")));
> {noformat}
> However, when it's consulted during establishing a connection, the default
> port number will have been filled in:
> {noformat}
> getMaxPerRoute(new HttpRoute(new HttpHost("localhost", 80, "http)));
> {noformat}
> The lookup for the maximum is by object equality, so this route will get the
> default of 2.
> The simplest change here is to fail when an unspecified port is passed in, to
> indicate that this is not supported. Alternatively, pass all {{HttpHost}}
> ports through {{DefaultSchemePortResolver.INSTANCE}} before using them as
> keys in a map.
