POST request not getting cached

[chiragmongia]

I want to cache a POST request for 5 minutes. My POST request entry looks like below-

toolbox.router.post(/myPostApi/, toolbox.cacheFirst, {
    cache: {
        name: 'myCache',
        maxAgeSeconds: 300
    }
});

This is not getting cached. The entries for GET requests in exact similar syntax are working fine. Am I missing something?

Ref: W3C discussion on caching POST requests. Nothing in the toolbox is wrong, this just isn't allowed by the current specification.

I think the best course here is to clarify in our docs that anything beyond GET or HEAD (if web browsers support HEAD) is capable of being cached. As browsers only really support POST otherwise and they are incapable of being cached currently.

@Garbee Thanks! The w3c service worker discussion makes sense.
