#Go HTTP Cache Transport

This package implements http transport functionality compatible with that of the Go standard library http.RoundTripper interface but which saves responses to disk locally based on very basic (at the moment) caching logic.

The simplest way to use is by overriding the http.DefaultTransport.

package main

import (
	"fmt"
	"net/http"
	"time"

	"git.sr.ht/~mariusor/cache"
)

const uri = "https://example.com"

func main() {
	// Use std library http.DefaultTransport, and save cached requests to /tmp
	http.DefaultTransport = cache.Shared(http.DefaultTransport, cache.FS("/tmp"))

	r, err := http.Get(uri)
	if err != nil {
		panic(err)
	}

	fmt.Printf("Get %s: %s\n", uri, r.Status)
	fmt.Printf("From cache: %t\n", cache.FromStorage(r))
	if age := cache.Age(r); age > 0 {
		fmt.Printf("Age: %s\n", age)
	}
}
