Oleg Kalnichevski commented on HTTPCLIENT-1575:
-----------------------------------------------

May I suggest a slightly different approach? How about disallowing HttpRoute 
instances without explicit target port? The port check would need to be 
performed in the HttpRoute constructor instead of  
PoolingHttpClientConnectionManager#setMaxPerRoute.

> {{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.
