| Hi Holger, Many thanks for this hint. I guess I will need to follow up with Openshift/RedHat. I have posted a question in the forum there, but so far no feedback: https://stackoverflow.com/questions/44134775/how-to-suppress-http-connection-keep-alive-header-in-response. |
Which openshift version do you use?
I have also added this question to the stackoverflow question.
| Thanks also for the advice to upgrade. I'm not sure if that is easy or even possible in Openshift online. Maybe their next version of the platform (v3) will have a more recent version of HAProxy. Would be nice, because I am also missing some of the config options that were added in later versions. |
In openshift v3 is haproxy 1.5.18 (rh rpm) in place.
The configfile for the openshift router can be found on github.

If you want to use it on premise you can replace it with your own.

As lukas written in this message below you will need to modify the haproxy config, which you can't on openshift online.

For the openshift router are some values which can be used to configure haproxy.

Side note: The *COMPRESSION* was my contribution ;-)))
Kind regards, Mats |
