ASP.NET の POST は最大で 1000 個


The Microsoft security update that security bulletin MS11-100 addresses changes the default maximum number of form keys, files, and JSON members that ASP.NET will accept in a request to 1,000. This change was made to address the Denial of Service vulnerability that the Microsoft security bulletin MS11-100 documents.

  • 対応は aspnet:MaxHttpCollectionKeys で任意の数を設定
  • ASP.NET 1.1 はレジストリ MaxHttpCollectionKeys を編集
  • JSON は aspnet:MaxJsonDeserializerMembers で設定
