Getting the response time for multithreaded client
Hi all!
We are using the Commons HttpClient in a multithreaded application, and
frequently there are more threads trying to use the client than the
limit set by setMaxConnectionsPerHost.
In this situation we still need to log the response time from the
server. How can we do that? Measuring the Method.executeMethod call
includes the time the thread sleeps before actually submitting the
request.
We are currently using Commons HttpClient 3.1 which I believe is the
latest stable release.
Any help is greatly appreciated, even quick fixes and hacks :)

The simplest way would be to register a request interceptor to log the
start time of the request execution and a response interceptor to log
the time a response head (but not the response body) has been received

Yes I could, but this example should be good enough to get you started

Depends on your definition of reliability. 4.0 is certainly not API
stable yet.

Hi Oleg!
Thank you for your answer.
How would I do it in HttpClient 4.0? Could you write a minimal example?
How reliable is HttpClient 4.0 compared to HttpClient 3.1?

Uwe,
There is no way around either upgrading to HttpClient 4.0, which has a
massively better, modular architecture or hacking the source code of
HttpClient 3.x
