[85] [DFN[[[XHR]]]] ([DFN[[CODE(DOMi)@en[[[XMLHttpRequest]]]]]]) は、
[[XML]] を含む様々なデータを [[HTTP]] を含む [[Web]] の[[プロトコル]]を使って、
[[要求]]を送信して[[応答]]を受信する [[API]] です。

* 代替

[117] 新規開発では [[XHR]] より [[fetch]] を使うのが好ましいと考えられます。
[[XHR]] の方がより近代的な [[API]] で使いやすく、高機能です。

[125] [[XHR]] への新機能の追加は凍結されています。

* 歴史

** Microsoft による開発

[87] [[Microsoft]] が [[IE]] から [CODE(DOMi)@en[[[ActiveXObject]]]]
によってアクセスできる [[API]] として実装しました。

** 普及

[88] [[Mozilla]] は [[XML Extras]] として [[XHR]] を実装しました。
この時 [CODE(DOMi)@en[[[ActiveXObject]]]] としてではなく、
[CODE(DOMi)@en[[[XMLHttpRequest]]]] [[コンストラクター]]として実装されました。

[89] [[Safari]] ([[WebKit]]) と [[Opera]] ([[Presto]]) も追随しました。

** WHATWG での標準化

[90] [[Ian Hickson]] は [[WHATWG]] 設立直後の2004年に [[Web Applications 1.0]]
(現在の [[HTML Standard]]) の一部として [[XHR]] を仕様化しました。

** W3C での開発

[91] その後 [[annevk]] が [[W3C]] [[WebApps WG]] で [[XHR]]
の標準化を行うこととなり、 [[Web Applications 1.0]] からは削除されて移管されました。

[92] [[WebApps WG]] では [[CORS]] をはじめ多くの新機能が開発されました。

[93] [[Microsoft]] による [[CORS]] ではなく [CODE(DOMi)@en[[[XDomainRequest]]]]
の実装、 [[CORS]] と [[UMP]] との対立、 [[XHR]] Level 1 と Level 2
の並行開発に関する混乱など、必ずしも順調ではありませんでしたが、
[[Microsoft]] を含む全 [[Webブラウザー]]で [[XHR]] は仕様書にある形で実装されるよう徐々に収束してはいきました。

]REFS]

** WHATWG XHR Standard

[94] [[W3C]] の手続きに関する [[annevk]] との対立がきっかけで [[XHR]]
は [[WHATWG]] に移り、[[Living Standard]] モデルで開発が進められることになりました。

[95] 当初 [[WebApps WG]] は [[WHATWG]] 版の変更に追随する形で同内容で出版する方針でしたが、
意味のない作業であり、うまくいかなかったようです。結局 (かなり古い版である)
Level 1 の [[W3C勧告]]を出版し、 (比較的新しい版である) Level 2 は [[WG Note]]
として出版することで廃案とし、以後の開発は完全に [[WHATWG]] に委ねることとなりました。

** Fetch

[96] [[CORS]] や [[HTML]] の [[fetch]]、[[XHR]] の内部処理部分を統合した [[WHATWG]]
[[Fetch Standard]] が [[annevk]] により新たに開発されました。 [[Service Worker]]
の開発の流れで [CODE(DOMm)@en[[[fetch]]]] [[API]] が追加され、 [[XHR]]
よりも [CODE(DOMm)@en[[[fetch]]]] がより根源的な [[API]] であると認識されるようになりました。

[97] そのため2014年以後 [[XHR]] に新機能は追加されなくなっています。

>セキュリティ上の配慮から、XMLHttpRequestがリクエストを送信できるのは同一ドメイン内に制限されています。この制限を超えたリクエストを行おうとすると、IE/Geckoではopenメソッド呼び出し時に、Operaではsendメソッド呼び出し時にエラーとなります(throwされるものはブラウザ毎にバラバラですが)。KHTMLでは特にエラーらしい挙動は無いようです。

;; 厳密に言えばIE+MSXMLは『MSXML Client Security』に従い、ローカルファイルからはあらゆるリソースに対してリクエストを発行できます。しかしWindows XP SP2環境ではデフォルトで実行がブロックされるはずです。WSHやHTAから実行する場合には制限はありません。 

[32] 
>XMLHttpRequestが送信するHTTPリクエストは、setRequestHeaderメソッドを使って書き換えたり、sendメソッドの引数として値を渡したりしない限り、ブラウザが送信するものと全く同一と言えます。ごく僅かの例外として、MSXMLではIEと比較してAcceptヘッダの内容が * に変わっているとか、MSXMLとOperaではスクリプトを呼び出したページのURLがRefererとして送信されるとか、その程度の違いはありますが、基本的にサーバサイドではブラウザからのアクセスなのかXMLHttpRequestを通したアクセスなのか区別する術はありません。

- もちろん、普段はちゃんと動いています。
- [KBD[読込み]]ボタンを押さなければ (つまり 
[CODE(DOMi)@en[[[XMLHttpRequest]]]] を使わなければ)
問題ありません。
- 読込んでいるのは自分自身ですが、
自分か他の文書かは余り関係ないようです。
- [CODE(XMLa)@en[[[onclick]]]] 属性の有無が1つの再現条件のような気がします。
- [CODE(XMLa)@en[[[xmlns]]]] 属性の有無が1つの再現条件のような気がします。
- でも決定的な条件はよく分かりませんでした。
