Sorry for being late to respond.
There is so much that’s being discussed that does not reflect in the wiki –
people like me think the wiki is the canonical document.
I like max’s approach but need to cache only in the next GET. Mostly
because some XMLHTTP post request under the same location directive will
invalidate and recache in this context. But that might not be a candidate
to recache. E.g. storing page performance counters after a page’s been
Can that be done with your approach? Just to invalidate?
I might sound a bit naïve here, but all the different proxy_cache
mechanisms seems to get a bit confusing.
To the reason why I don’t want nginx_ngx_cache_purge: Recompiling and
delivering through the yum repo of a large organization is a cumbersome
process and raises many flags.
