3. On the Toolbox tab, click Content Types.
4. On the toolbar beneath Content Types, click New.

6. (Optional) In Description, type a description for the content type.
7. In Available types, do one of the following:
   • To select an existing content type, click a file name extension or Multipurpose Internet Mail Extensions (MIME) type.
   • To add a new content type, type a new file name extension or a MIME type.
8. Click Add.

Note

• To open ISA Server Management, click Start, point to All Programs, point to Microsoft ISA Server, and then click ISA Server Management.

Important

• When you create content types, we recommend that you specify the content's MIME type and file name extension.
• When you configure a content type and specify the MIME type, you can use an asterisk (*) as a wildcard character. For example, to include all application types, enter application/*. The asterisk wildcard character can be used only with MIME types (and not with file extensions). The asterisk can be specified only once, at the end of the MIME type after the slash mark (/).
• To remove a file name extension or MIME type from the content type, in Selected types, click the file name extension or MIME type, and then click Remove.
• For ISA Server 2006 Enterprise Edition, array-level content types can be used only for array-level access rules.
• For ISA Server 2006 Enterprise Edition, enterprise-level content types cannot be modified at the array level. Furthermore, you must have Enterprise Administrator permissions to modify them.
• For HTTP requests, incoming content is identified by MIME type. When MIME information is missing, or when FTP is used, content is identify by file type (extension).
• After you click Apply in the details pane, the policy is updated. The new policy applies only to new connections.
