Hi ! I have an issue with my TS setup. My use case is that I want to cache images in TS and keep them for a very long time and only go back to origin if needed (which is indicated by the client request). Caching basically works for me if I set proxy.config.http.cache.required_headers=0 as my origin server doesn't supply lifetime values. My issue is that sometimes the images changes and than I need to get a fresh copy from origin. So I tried to use "Cache Control:no-cache" header to obtain a new copy but TS still gives me the old version. I cannot use any time based triggers to obtain a new copy from origin as the images are more or less static (99% of the time) but there are exceptions where the client specifies with the Cache Control header to revalidate the data with origin.
I tried it with 5.3.x and now also with 6.2.0. anyone knows what could be wrong ? yours Arnold
