I don’t think I made that clear.

To put it simply, Invalidate cache for a particular key entry but not all
of the cache

e.g for

location = /vehicles {

proxy_cache_key $request_uri;

}

Hashtable for cache:

[

hittp://jj.com/vehicles/cars => hittp://jj.com/vehicles/cars

hittp://jj.com/vehicles/bus => hittp://jj.com/vehicles/bus

hittp://jj.com/vehicles/bike=> hittp://jj.com/vehicles/bike

]

I should be able to invalidate just cars because my page for cars have
changed but not others.

Hope you got the point.
