説明

Web.configのrequireSSL属性値を「true」に設定すると、スクリーンショットの先読み生成が正しく動作せず、さまざまな問題を引き起こす恐れがあります。

<authentication mode="Forms">
 <forms loginUrl="member_login.aspx" cookieless="UseCookies" requireSSL="true" path="/MyApplication" />
</authentication>

例えば、パッケージ生成が失敗し、以下のエラーが出力されます：

Message: The application is configured to issue secure cookies. These cookies require the browser to issue the request over SSL (https protocol). However, the current request is not over SSL.

解決策

この問題を解決するには、スクリーンショットの先読み生成を無効にします。

Sitecore XPバージョン8.0初期リリース～バージョン8.1 Update-2の場合：

\App_Config\Include\Content Testing\Sitecore.ContentTesting.configファイルを開き、次の行にコメントを追加します：

<event name="item:saved">
  <handler type="Sitecore.ContentTesting.Events.GenerateScreenshot, Sitecore.ContentTesting" method="OnItemSaved">
    <excludeFields hint="list:ExcludeFieldFromComparison">
      <created>__created</created>
      <createdby>__created by</createdby>
      <updated>__updated</updated>
      <updatedby>__updated by</updatedby>
      <revision>__revision</revision>
      <sortorder>__sortorder</sortorder>
      <validfrom>__valid from</validfrom>
      <workflow>__workflow</workflow>
      <workflowstate>__workflow state</workflowstate>
      <lock>__lock</lock>
      <pageleveltestsetdefinition>__Page Level Test Set Definition</pageleveltestsetdefinition>
    </excludeFields>
  </handler>
</event>

<event name="item:saved:remote">
  <handler type="Sitecore.ContentTesting.Events.GenerateScreenshot, Sitecore.ContentTesting" method="OnRemoteItemSaved">
    <excludeFields hint="list:ExcludeFieldFromComparison">
      <created>__created</created>
      <createdby>__created by</createdby>
      <updated>__updated</updated>
      <updatedby>__updated by</updatedby>
      <revision>__revision</revision>
      <sortorder>__sortorder</sortorder>
      <validfrom>__valid from</validfrom>
      <workflow>__workflow</workflow>
      <workflowstate>__workflow state</workflowstate>
      <lock>__lock</lock>
      <pageleveltestsetdefinition>__Page Level Test Set Definition</pageleveltestsetdefinition>
    </excludeFields>
  </handler>
</event>

Sitecore XPバージョン8.1 Update-3以降の場合：

\App_Config\Include\Content Testing\Sitecore.ContentTesting.PreemptiveScreenshot.configファイルを無効にします。
