Subject Regression in JMeter 3.0 : Compressed response break keepalive
Date Wed, 11 May 2016 20:30:43 GMT
We have an issue in current 3.0 rc4 as seen by Rainer :

The issue is due to a behavioral change in HttpClient 4.5.2 vs

   - ResponseContentEncoding removes 3 headers from Response :
   Content-Encoding, Content-Length, Content-MD5
   - JMeter uses DefaultRequestDirector which is replaced by MainClientExec

Now here is what happens:

At this line, PostProcessor run , leading to removal of 3 headers


At the next line, keepAlive management is run, but it's too late as headers
have been removed:


While in new HC Class ProtocolExec:

The keepAlive is managed in this

Which calls this:

And Compression is managed afterwards in :

So no issue in HC4.5.2, but in JMeter. I think it's unfortunately a stopper
for the release.

Breaking KeepAlive is a big issue
