I've recently started to notice that some requests made by ATS to my origin servers are completely missing the Cache-Control header in the response. Functionality seems unaffected, but the missing header is somewhat concerning. Wondering if others have seen this behavior too as I'm having a heck of a time tracking down the cause.
Things I've done recently which may have caused this: * upgraded ATS from 3.0.4 to 4.1.2 * switched remap.config from using map/reverse_map combos to one way map + pristine host headers * using rfc5861 plugin for stale-while-revalidate and stale-if-error functionality Brendan Webb Web Engineer Oregon Health & Science University
