Joakim Erdfelt commented on HTTPCLIENT-2409:
--------------------------------------------
If your client does automatic response content decoding, and doesn't change the
representation of that response content in it's headers, then you have a client
that is inappropriate to use in a proxy scenario.
> Content-Length header not removed/modified when decompressing
> -------------------------------------------------------------
>
> Key: HTTPCLIENT-2409
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2409
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 5.6
> Reporter: Cristian Vat
> Priority: Major
>
> When decompressing gzip or other compression schemes the Content-Length
> header is not modified/removed anymore as it was before, this can lead to
> unexpected behaviors like truncation depending on caller behavior.
>
> Originally thought it was a spring issue with RestClient as
> https://github.com/spring-projects/spring-framework/issues/36064
> Summary:
> * Content-Encoding: gzip
> * Content-Length: 9075
> * actual read content if reading fully: 56815
>
> It's a combination of Spring and HttpClient behaviors but it lead to
> truncation at the compressed content length.
> I checked JDK HttpClient and Jetty HttpClient and they remove the
> Content-Length header if doing decompression.
> The same seems to have been the case in HttpComponents HttpClient but then
> the code that removed the headers was removed on 20th October in
> [https://github.com/apache/httpcomponents-client/commit/56122fd33fb8a67d23369a81f6e1d89aabf4ba10]
