Vercel uses HTTP caching

original text : https://blog.imlete.cn/article/Vercel-Use-HTTP-Cache.html

Recently, I am also bored , Just turn it over Vercel file , So I found out , It can actually customize the response header ( Static file deployment can )

From my personal point of view , I thought I had to use ServerLess Ability to use http The response object of specifies the response header information , little does one think Vercel It can be passed directly vercel.json File specifies the configuration

The blog I deployed ( Or other static sites ) Isn't it possible to start http Cached ？

Vercel file : https://vercel.com/docs/project-configuration#project-configuration/headers

The following is the use of this site vercel.json file information ( The cache is on 1 God )

{
    
  "headers": [
    {
    
      "source": "/sw.js",
      "headers": [
        {
    
          "key": "Cache-Control",
          "value": "public, max-age=0, must-revalidate"
        }
      ]
    },
    {
    
      "source": "(.*)",
      "headers": [
        {
    
          "key": "Cache-Control",
          "value": "public, s-maxage=86400, max-age=86400"
        }
      ]
    }
  ]
}
