Hi:
We are experiencing low cache hit ratio in Nginx server. It turned out
that one reason is client may be sending the same requests with
parameters in different orders.
e.g.
foo?p1=a&p2=b&p3=c
foo?p2=b&p1=a&p3=c
And our cache key is set as
proxy_cache_key $uri$is_args$args;
It is not feasible to change all clients to resort their urls. Is
there any way in Nginx to address that?
Thanks,
-Wei
