I moved my installation from the old stable 0.7.x branch to the new stable 0.8.x and cannot proceed as I get an error message saying proxy_cache_bypass must be used along with proxy_no_cache since v0.8.46. However, it seems proxy_cache_bypass is not documented anywhere (can't find it on the wiki anyway apart from one statement in the 0.8.46 changelog listing it as a new feature).

Can anyone kindly point me to where I can find documentation on this?

Thanks
