[cache-bundle] Additional Content-Types to cache-bundle.json

API

• Cache any content types other than text/html, text/javascript, image/svg+xml
  • Optional headers to include in cache response headers
    • hook.parameters.significantHeaders = { "Header-Name": true }
  • Additional Cacheable Content-Types
    • hook.parameters.cacheableContentTypes = { "text/css": true, "image/png": true, ... }
      • Note: text/html, text/javascript, image/svg+xml must not be included here
  • Callback to Validate Cacheable URL
    • hook.parameters.validateCacheableUrl = function (url, contentType)
      • url: String: target URL to validate
      • contentType: String: normalized Content-Type without charset
      • return a truthy value if url with contentType is cacheable
      • If the callback function is undefined, any contentType values within hook.parameters.cacheableContentTypes are cacheable
• Extended Metadata Format in cache-bundle.json

  cacheBundle = {
    "version": "version_123", // cache version
    "url?param=1": "body in string", // concise format for string data for .js, .html, .json, .svg; equivalent to { "body": "body in string", "Content-Type": "{type}" }
    "url?param=2": {
      "Location": "url?param=1", // link to the other content
      "Location": "data:image/jpeg;base64,...", // encoded body data; Note: "Location" appears only once in a metadata object, of course
      // If Non-dataURI "Location" exists, other metadata entries are ignored
      "Content-Type": "text/xml", // MIME type
      "body": "body in string", // content body
      "Other-Headers": "header value", // HTTP headers
    },
  }
