Oleg Kalnichevski resolved HTTPCLIENT-1823.
-------------------------------------------
Resolution: Fixed
Fix Version/s: (was: 5.0)
5.0 Alpha2
Async message entity content manipulation should be possible as of 5.0a2. See
examples:
https://github.com/apache/httpclient/blob/trunk/httpclient5/src/examples/org/apache/hc/client5/http/examples/AsyncClientInterceptors.java
https://github.com/apache/httpclient/blob/trunk/httpclient5/src/examples/org/apache/hc/client5/http/examples/AsyncClientMessageTrailers.java

> Key: HTTPCLIENT-1823
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1823
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Reporter: Sven Zethelius
> Fix For: 5.0 Alpha2
>
>
> Examples show how to do GZIP compression in sync HttpClient (
> https://hc.apache.org/httpcomponents-client-4.2.x/httpclient/examples/org/apache/http/examples/client/ClientGZipContentCompression.java),
> but even thought AsyncHttpClient supports registering the same
> HttpRequestInterceptor and HttpResponseInterceptor they can only modify the
> headers. Doing any modification of the entity, which is necessary to do
> compression ends up being ignored.
> In HttpRequestInterceptor, this is because A) BasicAsyncRequestProducer is
> registerd early in the lifecycle with a reference to the original request
> entity which it uses to write the content. B) The wrapping request entity
> passed to the interceptor doesn't pass calls to setEntity back to the request
> it's wrapping.
> In HttpResponseInterceptor, the entity of the HttpResponse is bypassed
> completely by BasicAsyncResponseConsumer.
> This means clients of AsyncHttpClient have no way to intercept the message.
> My request is that there needs to be a way to intercept and manipulate the
> request bytes in/out so that compression can be implemented.
