Appendix B. Browser-Hosted Applications

As described in Requirement 1.10 in this Server Specification, clients that ship as part of distributed applications must comply with the desktop application specification for Windows 2000 in order for the application to be certified. However, special considerations apply for browser-hosted applications:

  • Clients that are browser-hosted Web pages, use only pure HTML and DHTML, and contain no executable content (e.g., no ActiveX or Java controls) need not be tested for full compliance with the Desktop Application Specification, because they will, for the most part, inherit the compliance of their host browser. However, these browser-hosted clients are required to meet the following two specific requirements:
    • Provide documented keyboard access to all features

    • Do not rely exclusively on sound.

      For information on designing accessible Web content, see "Web Content Accessibility Guidelines" at

  • Browser-hosted clients that include executable content, such as ActiveX or Java controls, must comply with the requirements in the Desktop Application Specification indicated on the checklist below.

Note   Some requirements below may not apply to your application, if your application does not expose functionality covered by the requirement. For example, if your application does not expose file names to the user, then Requirement 1.3 does not apply.

   Windows Fundamentals
X 1.1 Perform primary functionality and maintain stability
X 1.2 Provide 32-bit components
X 1.3 Support Long File Names and UNC paths (if you expose file names)
X 1.4 Support printers with long names and UNC paths (if you support printing)
X 1.5 Do not read from or write to Win.ini, System.ini, Autoexec.bat or Config.sys on any Windows operating system-based on NT technology.
X 1.6 Ensure non-hidden files outside of your application directory have associated file types, and all file types have associated icons, descriptions, and actions
X 1.7 Perform Windows version-checking correctly (if you need to determine the Windows version)
X 1.8 Support AutoPlay of compact discs (if you distribute your product on CD)
X 1.9 Kernel mode drivers must pass verification testing on Windows 2000 (if you have any)

Component Sharing
X 3.1 Do not attempt to replace files that are protected by System File Protection
3.2 Component producers-Build side-by-side components
3.3 Application developers-Consume and install side-by-side components
X 3.4 Install non-side-by-side shared files to the correct locations
