[17] 終点要求終点の分類

文脈

[18] 終点要求終点が参照される場面

[37] fetch で使われる要求の終点の値は、 fetch の呼び出し元で決定されます。

[35] Request オブジェクトには destination IDL属性 (プロパティー) があって要求の終点を参照できます。 しかし Request コンストラクターや fetch メソッドの引数にこれに相当するものはなく、 スクリプトから終点を明示的に指定する方法はありません。

[36] <link rel=preload> などで使われる <link as> 属性には potential destination を指定することになっています。 これを通じて間接的に終点を指定することはできます。

関連

[12] potential destination なるものもありますが、 少し認められる値が違います。

歴史

導入

[3] 要求終点は、要求文脈を細かく分解した結果導入されました。

The value associated with this key is an array of strings representing the resource types that the rule should match. If not specified, the rule matches all resource types. The strings describes how the browser intends to use the resource, not necessarily the type of the resource itself. For example, <img src="something.css"> is identified as an image. Valid values for resource-type are:

document

image

style-sheet

script

font

raw (Any untyped load, such as XMLHttpRequest)

svg-document

media

popup

型の吸収

[15] 終点要求終点が細分化された結果、型要求型と区別する必要がなくなったとして、 両者は統合されました。
