+# Caching
+
+## Revalidating the cache
+
+Invalidate cache can be done at two levels using tags:
+
+-   Data fetching cache
+-   Rendering cache
+
+To invalidate and refetch the data cache, you can execute a POST request to `/~/gitbook/revalidate`:
+
+```bash
+curl --location --request POST 'https://gitbook/mycompany.com/~gitbook/revalidate' \
+--header 'Content-Type: application/json' \
+--data-raw '{"tags": ["space.id"]}'
+```
+
+To invalidate the rendering cache, the implementation mainly depends on the infrastructure serving the content, GitBook outputs a `Cache-Tag` header on every requests. The value of the header is a comma separated list of tags.
+
+## Purging the cache
+
+Purging the cache, without revalidating, is done by passing `"purge": true` in the request body.

+# `@gitbook/cache-do`
+
+Cache backend, powered by Cloudflare Durable Objects. The cache is optimized for GitBook use-cases.
+
+### Performances
+
+The cache backend is optimized for performances by being distributed and accessible close to the worker locations that are reading it.
+
+### Geo-distribution
+
+To achieve a good balance between **performances** and **consistency**, cache objects are distributed over 7 locations, representing continents.
+
+It makes it possible to purge all 7 locations in one go and achieve fast consistency.
+
+### Concepts
+
+**Cache tag**: unique tag in the cache environment. A cache tag groups multiple keys that should be purged together in one operation.
+Cache tags should not contain a large set of unique keys. Exceeding thousands could lead to performances or reliability issues.
+
+**Cache key**: unique key in the cache environment. Each key should be assigned to a `tag`.
+
+**Location**: cache is distributed over 7 unique locations, one for each continent.
