Control caching behavior

Web clients can cache resources from a server. Afterwards, a client can access its local cache, which reduces the number of requests sent to the server.

Servers can instruct clients to implement caching in certain ways. Servers can also set separate caching policies for any intermediary proxies in-between the server and the client.

Reblaze is a proxy between the clients and the backend. When the backend responds to clients, the outgoing responses pass through Reblaze. You can instruct Reblaze to preserve or alter the caching instructions in those responses.

This can be done through Edge Functions. Out of the box, Reblaze includes several cache policy Edge Functions for this purpose. If you need additional assistance in customizing Reblaze's caching behavior, contact support.
