Mike Cumings commented on HTTPCLIENT-854:
-----------------------------------------

If this is the final position, I'm disappointed.  It appears as if this use 
case was known prior to 4.x development 
(http://wiki.apache.org/jakarta-httpclient/UseCases/SingleAsyncRequest) yet was 
not implemented.  Meanwhile, the 4.x API was implemented such that 
modifications to the API are not possible without breaking source and binary 
compatibility.  Additions to the API to work around this limitation are not 
being accepted, leaving options of waiting for long periods of time (e.g., for 
5.x) or implementing an entirely separate API built upon the NIO core (again 
requiring long periods of time as well as the application of significant 
engineering resource).  Is this a fair characterization?

httpclient is a very useful API and I thank the core team members for your 
contribution.  Hopefully this will get resolved in the future, sometime.  For 
now, I suppose I'll just have to code around this and hope that I can revisit 
the issue to remove the inefficiency, later.

> The HttpClient API currently provides for the execution of a request via the 
> HttpClient.execute(...) methods.  These methods all send the request and then 
> block until the response has been received.  This precludes the user of the 
> API from being able to send the request, perform some additional work, then 
> come back and block on the request.  This style of processing is very 
> desirable for implementation of HTTP-based protocols such as 
> Bidirectional-streams Over Synchronous HTTP (BOSH).   This capability is also 
> closely related to HTTPCLIENT-258, support for HTTP 1.1 pipelining.
> The current code base (4.0) currently utilizes 
> org.apache.http.impl.client.DefaultRequestDirector.execute(...) to transmit 
> requests.  This method contains a retry loop which blocks on and then 
> examines the response from the remote server.  When success is detected, it 
> cleans up and returns the response instance.  Requests are sent using an 
> HttpResponseExecutor instance.  These classes support the ability to 
> separately doSendRequest()  and doReceiveResponse().
> Please expose the ability to leverage this functionality outwith the retry 
> loop but including the existing routing and authorization capabilities, where 
> possible.
