Communities 用の Dispatcher の設定

AEM Communities

AEM Communities では、 コミュニティサイト が適切に機能するように Dispatcher を設定する必要があります。コミュニティの有効化やソーシャルログインなどの機能を含める場合は、追加の設定が必要です。
特定のデプロイメントとサイトデザインにとって何が必要かについては

Dispatcher のキャッシュ

概要

AEM Communities 用の Dispatcher のキャッシュとは、Dispatcher によってコミュニティサイトのページの完全にキャッシュされたバージョンを提供する機能です。
現在、コミュニティサイトを閲覧するユーザー、検索の結果コミュニティページに辿り着いたユーザー、ページのインデックスを作成する検索エンジンなど、匿名のサイト訪問者に対してのみサポートされます。匿名ユーザーと検索エンジンのパフォーマンスが向上するという利点があります。
サインインしているメンバーの場合、Dispatcher はキャッシュをバイパスして、要求をパブリッシャーに直接リレーするため、すべてのページが動的に生成されて提供されます。
Dispatcher のキャッシュをサポートするように設定すると、TTL に基づく「max age」期限がヘッダーに追加され、Dispatcher にキャッシュされたページが最新に保たれます。

要件

設定

OSGi 設定「 ACS AEM Commons - Dispatcher Cache Control Header - Max Age 」で、指定されたパスに保存されるキャッシュされたページの有効期限を設定します。
  • From the Web Console
  • Locate ACS AEM Commons - Dispatcher Cache Control Header - Max Age
  • 新しい接続設定を作成するには、「+」アイコンを選択します
  • フィルターパターン
    (必須) コミュニティページへの1つ以上のパス。 例: /content/sites/engage/(.*)
  • Cache-Controlの最大経過時間
    (必須) # ヘッダに追加する最大経過時間(秒)。 この値はゼロ(0)より大きくする必要があります。

Dispatcher クライアントヘッダー

In the /clientheaders section of dispatcher.any , if listing a specific set of headers, it is necessary to include "CSRF-Token" in order for the Enablement feature to work properly.

Dispatcher フィルター

dispatcher.any ファイルの /filter セクションは コンテンツへのアクセスの設定 - /filter に記述されています。
このセクションでは、Communities 機能を正しく機能させるために必要になる可能性があるエントリについて説明します。
フィルターのプロパティ名は、フィルターパターンの適用順序を示す 4 桁の数字を使用するという命名規則に従います。複数のフィルターパターンを 1 つの要求に適用した場合は、最後に適用されたフィルターパターンが有効になります。したがって、通常は、最初のフィルターパターンであらゆるものを拒否し、後続のパターンで何らかの規則性に基づいてアクセスを認めるという方法をとります。
以下のサンプルでは、プロパティ名を使用しています。特定の dispatcher.any ファイルに合わせて変更が必要な可能性があります。
関連トピック:
プロパティ名の例 All property names shown, such as /0050 and /0170 , should be adjusted to fit within an existing dispatcher.any configuration file.
以下のエントリを /filter セクションの最後に追加する必要があります(特にすべての拒否エントリの後)。

Dispatcher ルール

dispatcher.any のルールセクションは、要求された URL に基づいてキャッシュされる応答を定義します。Communitiesの場合、ルールセクションは、キャッシュしない対象を定義するために使用します。
# Never cache the client-side .social.json calls
/0001 { /type "deny" /glob "*.social.json*" }

# Never cache the user-specific .json requests
/0002 { /type "deny" /glob "/libs/granite/csrf/token.json*" }
/0003 { /type "deny" /glob "/libs/granite/security/currentuser.json*" }
/0004 { /type "deny" /glob "/libs/granite/security/userinfo.json*" }

# Never cache the private community groups pages in case - add your own deny rules in there
/0005 { /type "deny" /glob "/content/*/groups/*" }

# Never cache the assignments page in case the Enablement feature is in use - add your own deny rules in there
/0006 { /type "deny" /glob "/content/*/assignments/*" }

# Never cache user generated content
/0208 { /type "deny" /glob "/content/usergenerated/*" }

トラブルシューティング

よくある問題の原因は、フィルタールールを挿入するときに、以前のルールへの影響を考慮しないことです。特に、アクセスを拒否するルールを追加するときには注意が必要です。
通常は、最初のフィルターパターンであらゆるものを拒否し、後続のフィルターで何らかの規則性に基づいてアクセスを認めるという方法をとります。リクエストに複数のフィルターが適用される場合、適用される最後のフィルターが有効になります。

dispatcher.any のサンプル

以下は、Communities の /filters と /rules が含まれる dispatcher.any のサンプルファイルです。
# Each farm configures a set of load balanced renders (i.e. remote servers)
/farms
  {
  # First farm entry
  /website
    {
    # Request headers that should be forwarded to the remote server.
    /clientheaders
      {
      # Forward all request headers that are end-to-end. If you want
      # to forward a specific set of headers, you'll have to list
      # them here.
      "*"
      }

    # Hostname globbing for farm selection (virtual domain addressing)
    /virtualhosts
      {
      # Entries will be compared against the "Host" request header
      # and an optional request URL prefix.
      #
      # Examples:
      #
      #   www.company.com
      #   intranet.*
      #   myhost:8888/mysite
      "*"
      }

    # The load will be balanced among these render instances
    /renders
      {
      /rend01
        {
        # Hostname or IP of the render
        /hostname "127.0.0.1"
        # Port of the render
        /port "4503"
        # Connect timeout in milliseconds, 0 to wait indefinitely
        # /timeout "0"
        }
      }

    # The filter section defines the requests that should be handled by the dispatcher.
    #
    # Entries can be either specified using globs, or elements of the request line:
    #
    # (1) globs will be compared against the entire request line, e.g.:
    #
    #     /0001 { /type "deny" /glob "* /index.html *" }
    #
    #   matches request "GET /index.html HTTP/1.1" but not "GET /index.html?a=b HTTP/1.1".
    #
    # (2) method/url/query/protocol will be compared againts the respective elements of
    #   the request line, e.g.:
    #
    #     /0001 { /type "deny" /method "GET" /url "/index.html" }
    #
    #   matches both "GET /index.html" and "GET /index.html?a=b HTTP/1.1".
    #
    # Note: specifying elements of the request line is the preferred method.
    /filter
      {
      # Deny everything first and then allow specific entries
      /0001 { /type "deny" /glob "*" }
