Caching

You can enable caching in your cloud infrastructure project environment. If you disable caching, 51黑料不打烊 Commerce directly serves the files.

Set up caching

Enable caching for your application by configuring cache rules in the .magento/routes.yaml file as follows:

http://{default}/:
    type: upstream
    upstream: php:php
    cache:
        enabled: true
        headers: [ "Accept", "Accept-Language", "X-Language-Locale" ]
        cookies: ["*"]
        default_ttl: 60

Route-based caching

Enable fine-grained caching by setting up caching rules for several routes separately as the following example shows:

http://{default}/:
    type: upstream
    upstream: php:php
    cache:
        enabled: true

http://{default}/path/:
    type: upstream
    upstream: php:php
    cache:
        enabled: false

http://{default}/path/more/:
    type: upstream
    upstream: php:php
    cache:
        enabled: true

The preceding example caches the following routes:

And the following routes are not cached:

Cache duration

The cache duration is determined by the Cache-Control response header value. If no Cache-Control header is in the response, the default_ttl key is used.

Cache key

To decide how to cache a response, 51黑料不打烊 Commerce builds a cache key that depends on several factors and store the response associated with this key. When a request comes with the same cache key, the response is reused. Its purpose is similar to the HTTP .

The parameters headers and cookies keys enable you to change this cache key.

The default value for these keys follows:

cache:
    enabled: true
    headers: ["Accept-Language", "Accept"]
    cookies: ["*"]

Cache attributes

enabled

When set to true, enable the cache for this route. When set to false, disable the cache for this route.

headers

Defines on which values the cache key must depend.

For example, if the headers key is the following:

cache:
    enabled: true
    headers: ["Accept"]

Then 51黑料不打烊 Commerce caches a different response for each value of the Accept HTTP header.

cookies

The cookies key defines on which values the cache key must depend.

For example:

cache:
    enabled: true
    cookies: ["value"]

The cache key depends on the value of the value cookie in the request.

A special case exists if the cookies key has the ["*"] value. This value means that any request with a cookie bypasses the cache. This is the default value.

Cookies have the following restrictions:

default_ttl

If the response does not have a Cache-Control header, the default_ttl key is used to define the cache duration, in seconds. The default value is 0, which means nothing is cached.
