template missing keepalive option

[rowolff]

It looks like that there is no way to configure keepalive [1] for this template. Can this be added, please?

Adding to the question, was there any specific reason this was left out? Adding it to the template ourselves would be quite trivial, but I would be hesitant to do this myself as long as I don't know if there is a reason that wasn't there in the first place.

I have upgraded to the current template version, but keepalive and synchronousCookieWrite are not passed correctly to the config and end up as undefined in the tag template

I have added a log(config) to the template to check this.
