MIME Types

With the MIME Types form, you can create or modify a list of file extensions that you want to bind to MIME (Multipurpose Internet Mail Extensions) content types or subtypes. File contents are packaged using methods defined by the MIME extensions standard. You can use a list to associate file extensions with MIME types/subtypes. The server considers any file with an extension matching an entry in this list to be packaged with the associated MIME type or subtype.

There are two special extension patterns that you can include in the list:

*.* matches all file names that contain a period and have not been matched by other entries in the list
* matches all file names that do not contain a period and have not been matched by other entries in the list

You can also define whether you want your server to differentiate between upper-case and lower-case letters in file extensions.

Setting Case Sensitivity

You can define whether you want your server to differentiate between upper-case and lower-case letters on file extensions. For example, if case sensitivity is selected, the extension PS would be interpreted as different from the extension ps.

The setting for case sensitivity applies to all extensions. If you change the setting on this form, the change also applies to the MIME Encodings form.

Organization of MIME Entries

It might be useful for you to organize the list of MIME entries in a certain order, for example, to arrange the entries according to extension or encoding type. To do this, you must maintain the proper index order when inserting, replacing, and removing entries in the list. The index is used for your reference and organization; you should order it so that it is useful to you.

You might also want to arrange entries based on the quality of the MIME encoding by using the Quality field on the form. If there are multiple representations of a file from which to choose, the server selects the file with the extension associated with the highest quality value. Using the Quality field is optional.
