Upload large content with Http.sys, IIS, ASP and ASP.NET

Posted on Updated on

There is a limit on the size of content (like files) one can upload when that content is hosted on an Internet Information Services (IIS) web server. The limits in charge depend on

  • The version of IIS
  • The configuration of IIS
  • The possible usage of certain ISAPI extensions and filters
    • If so, which extensions/filters? (for example: ASP or ASP.NET)
    • If so, which versions of extensions/filters (for example: version 4.0 of ASP.NET)
