The Mime Types page allows you to add, edit, or delete suffix mappings. Suffix mappings are used to map file extensions to MIME types (a method for determining file formats), so that the JavaServer can determine the type and contents of any HTTP file request it receives. The JavaServer uses the suffix mappings to determine how to return data to the World Wide Web client making the request.

This page displays a list of predefined suffix mappings. If JavaServer can't find a suffix mapping entry in this list, it uses the default MIME type text/plain. This means that the server uses the text transfer method and assumes that it is returning plain text.

Settings

Extension
A list of possible extensions that could be attached to any file request. For example, the .gif extension indicates that the requested file is of the type/subtype image/gif (Graphics Image Format).

Note: For easier suffix mapping and fielding of requests, it is possible to enter spelling variations for common extensions into the Extension list. For example, you could enter both gif and giff into the list as variations of the type/subtype image/gif. This way, the JavaServer will properly service requests for the file type even if the requesting suffix is misspelled.

Type/Subtype
A list of file types recognized by the JavaServer. The Type part of the pair indicates the generic file category possible to be served by the JavaServer, for example, audio, application, image, etc. The Subtype part of the pair indicates the exact file extension for that generic category.
