[view] [cache] Too restrictive cacheable condition as only HTTP 200 and GET are cacheable

[alquerci]

The view cache work well but suffer of a limitation in order to be compatible with HTTP specifications about cacheable status codes and methods.

Expected

• On Symfony4 pages with response 200, 203, 300, 301, 302, 404, 410 are cacheable with additional condition on the Cache-Control status.

• Be able to cache GET and HEAD methods.

Actual

• Only pages with HTTP 200 response can be stored on cache.
• Only response from GET method can be stored on cache.
