If server return 304, then redirected to null location error

[alvinlin123]

I am using Gatling (through maven) to test a CDN server. Whenever the CDN server returns 304, I see the following error:

[ERROR] [11/12/2013 18:12:30.603] [GatlingSystem-akka.actor.default-dispatcher-11] [akka://GatlingSystem/user/$j] URI http://localhost:8080/httpd/flicker/5497/10736165575_019600e371.jpg was redirected to null location

I think this bug is related to:
AsyncHttpClient/async-http-client#391

I am using the latest released version 2.0.0-M3a

OK.

You're absolutely right, you're hit by this AHC bug (I'm actually the one who fixed it).

• Either use AHC 1.7.21 (depending on how you use Gatling, either replace the jar in the bundle, or force the version from maven)
• or upgrade to Gatling snapshot (https://github.com/excilys/gatling/wiki/Continuous-Integration)

Cheers,

Stéphane
