# Object Caching

Tigris transparently caches the objects close to the user to provide low-latency access. The region chosen for caching the objects depends on the request pattern from the users. Objects stored in San Jose but requested frequently from Sydney will result in getting cached in the Sydney region. Caching is provided through a distributed global caching layer with cache nodes deployed in regions globally. This ensures that user requests can be served from the region closest to the user.

Object caching requires no configuration and is enabled by default on all buckets.

## Cache Headers[​](#cache-headers "Direct link to Cache Headers")

By default, Tigris honors the cache headers set by the user when writing the object, and returns those headers as part of the response when the object is fetched. This allows the user to control the caching behavior of the object.

### Public Buckets[​](#public-buckets "Direct link to Public Buckets")

Tigris sets default cache header for public buckets for static assets if no cache headers are provided by the user. The default cache header is set to `Cache-Control: public, max-age=3600`. This applies to the following static assets:
