Has anyone run Apache Traffic Server in production? I've used it
for a proof-of-concept before, and I like it overall, but I'm
about to recommend its use and would like to hear any horror stories.
I'm planning on using it as a reverse proxy cache for a site that
is expected to have a couple tens of thousands of active users at
peak. I'd have HAProxy in front for HA, with a mirror setup of
everything below it, talking to ATS, with another HAProxy behind
ATS for load balancing the origin servers.
Any comments welcome.
Most definitely NOT speaking as an expert but in my perambulations
around the web I have found mention of using nginx WITH apache2
specifically in some kind of a reverse proxy cache system/mode.

https://serverfault.com/questions/30705/how-to-set-up-nginx-as-a-caching-reverse-proxy
seems to have a fair amount of suggestions

https://guides.wp-bullet.com/how-to-configure-nginx-reverse-proxy-wordpress-cache-apache/
lots of setup stuff available here
I was using
nginx + apache2 + reverse proxy cache
in duckduck
apache2 + reverse proxy cache
seems to offer less proposals than the previous
Perhaps this coupling would work for you.
To add another data point I have used squid as a reverse proxy on a
couple of high traffic project over the years.
I wonder about caching and if there is a gain when you have multiple
back end servers.
If your caching proxy server pushes the data out to a disk cache then it
may not be much faster than getting the data from the directly connected
web server.
The proxy server is a operating off a single disk for that data where N
web servers are operating off of N disks.
One of the things to be said for a simple non-caching proxy like HAProxy
is that it is small and fast.
As soon as you start caching you need to handle lots of corner cases
like what to do with requests with big results.
