Internet Explorer Processes

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a Web server.

This policy setting determines whether Internet Explorer requires that all file-type information provided by Web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME sniff indicates that the file is really an executable file, Internet Explorer renames the file by saving it in the Internet Explorer cache and changing its extension.

If you enable this policy setting, Internet Explorer requires consistent MIME data for all received files.

If you disable this policy setting, Internet Explorer will not require consistent MIME data for all received files.

If you do not configure this policy setting, Internet Explorer requires consistent MIME data for all received files.

Supported on: At least Internet Explorer 6.0 in Windows XP with Service Pack 2 or Windows Server 2003 with Service Pack 1
