Hi

I'm running nginx as a reverse proxy for a website, and we have an occasional problem where one of the back end servers occasionally sends an errant 301 with caching headers as the home page for the site. nginx then caches this and responds to any requests with this redirect to the wrong place.

I've rtfm and clearly need to use proxy_no_cache and proxy_cache_bypass, but I'm none the wiser on how to actually format it for this, or indeed whether it's possible to control based on the http response code?

thanks
Pete
