IMPORTANT: This article contains information about editing the registry. Before you edit the registry you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.



SYMPTOMS
When you view a page from Personal Web Server, some objects may not be displayed correctly.



CAUSE
If the server does not know what the Multipurpose Internet Mail Extensions (MIME) type is for the requested data, it may return an incorrect type (such as text/plain) that results in an incorrect display of the object.

What Is a MIME Type?
MIME types instruct a Web browser (such as Microsoft Internet Explorer) how to handle files being downloaded from a server. When a Web browser requests an item on a server, it also requests the MIME type of the object. Some MIME types (such as graphics) can be displayed inside the browser, while others (such as animations or document files) must start an external program to display them.



WORKAROUND
To work around this problem, add the appropriate MIME types to Personal Web Server.

Steps to Add a MIME Type
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

The list of configured MIME types is stored in the following registry key:   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\InetInfo\ Parameters\MimeMap To add a new MIME type, open the MimeMap key and create a new String value. The name for the new string value should be set for the new MIME type in the following format:

,, ,

For example, type the following:

"image/gif,gif,,"

NOTE: The default entries contain settings in the second unused area. These settings are left over from the Internet Information Server (IIS) codebase, which Personal Web Server is based on, but they are not used.
