// Package main shows how you can use the `WriteWithExpiration`
|
|
// based on the "modtime", if it's newer than the request header then
|
|
// it will refresh the contents, otherwise will let the client (99.9% the browser)
|
|
// to handle the cache mechanism, it's faster than iris.Cache because server-side
|
|
// has nothing to do and no need to store the responses in the memory.
