If I change the proxy_cache_bypass parameter to contain no period characters, then the caching mechanism will work as expected without the cookie, and when the cookie is sent, the upstream_cache_status shows BYPASS as expected. I have checked all the RFC documentation on syntax of cookie name, and all the information I can find shows that a period character should be allowed in a cookie. I tried different workarounds to this, including encapsulating the cookie variable inside of quotes , eg : proxy_cache_bypass ""$cookie_Example.AUTH""; I have also tried escaping the period, eg : proxy_cache_bypass $cookie_Example\.AUTH; All of the workaround attempts failed, with upstream_cache_status showing BYPASS even though the browser/curl was not sending a a cookie. I realize that there are a lot of third party modules here, but I do not suspect that there is any conflict, and fully expect this bug to be present with only official nginx modules (proxy module specifically) being used.
