Hi Sebastian

One can simulate the effect of a slow network connection by temporarily 
blocking the communication thread with Thread#sleep() while uploading 
the request entity or/and downloading the response entity. There's no 
way I can think of to slow down the processing of request/response
headers, save forking the code, because HttpClient 3.0 does not expose 
the underlying HttpConnection instance to the request caller.

PS: there are dedicated HttpClient lists
httpclient-dev@jakarta.apache.org and httpclient-user@jakarta.apache.org
which you should write to when seeking assistance with HttpClient. I am
likely to be the only HttpClient committer who monitors this list. If
you want to address HttpClient / HttpComponents project community as a 
whole and get a more comprehensive response, please post your questions 
to one of the project's lists
