[question] how to define time how long should the cache live?

[str]

Hi!

It looks like my cache lasts for a very short time. This is how I define my cache middleware:

        $stack = HandlerStack::create();
        $stack->push(
            new CacheMiddleware(
                new PrivateCacheStrategy(
                    new FlysystemStorage(
                        new Local('./tmp/cache/guzzle/')
                    )
                )
            ),
            'cache'
        );
        $client = new Client([
            'handler'         => $stack,
            'allow_redirects' => false,
            'referer'         => true,
            'track_redirects' => true,
        ]);

how can I define how long my cache should last? Like in days?

@str You can set time like this.

new PrivateCacheStrategy(
	new FlysystemStorage(
		new Local('./tmp/cache/guzzle/')
    ), 60 // <= 60 seconds
)

Although my experience was, if the server doesn't return proper caching headers (for how long content is cache-able), then nothing really happens (beside a file being written, the network access happens anyway).

You can force caching with \GreedyCacheStrategy and then the caching time setting is honored. The middleware is also setting a Http Header, warning you:

guzzle-cache-middleware/src/Strategy/GreedyCacheStrategy.php

Line 67 in 5cd04b4

'Cached although the response headers indicate not to do it!',

Hope that helps someone, please correct me if I'm wrong.
