Hi All,
I want to use connection collapsing in my current configuration, but I'm
not sure, is it stable at the moment?
I think the connection collapsing feature was removed long ago. It was
deemed unstable, and unmaintainable. I don't think anyone is or plan on
working on it, but we certainly would accept such contributions :).
My current version:
Apache Traffic Server - traffic_server - 3.3.1-dev - (build # 11318 on

What else except proxy.config.cache.enable_read_while_writer and
background_fill_completed_threshold, would you recommend to configure in
case of configuration with connection collapsing.
read-while-writer, and the fuzzy "pre-revalidate" feature are both there to
alleviate the stampeding herd problem. The latter lets you configure a
"chance" for a client request to not be served out of cache, but instead go
to origin. You tell it when to start doing this, and what the percentage
chance is (e..g 5 minutes before expiration, and 0.1% chance).
