MIME settings

The MIME settings list a number of default common content types that are used when transmitting Multipurpose Internet Mail Extensions (MIME) messages. You can configure API Gateway's Content Type filter to accept or block messages containing specific MIME types. Therefore, the contents of the MIME types library act as the set of all MIME types that API Gateway can filter messages with.

All of the MIME types listed in the table are available for selection in the Content Type filter. For example, you can configure this filter to accept only XML-based types, such as application/xml, application/*+xml, text/xml, and so on. Similarly, you can block certain MIME types (for example, application/zip, application/octet-stream, and video/mpeg).

For more details on configuring the Content Type filter, see the API Gateway Policy Developer Guide.


To configure the MIME settings, in the Policy Studio main menu, select Tasks > Manage Gateway Settings > General > MIME. Alternatively, in the Policy Studio tree, select the Environment Configuration > Server Settings node, and click General > MIME. To confirm updates to these settings, click Apply changes at the bottom right of the screen.

The MIME settings screen lists the actual MIME types on the left column of the table, together with their corresponding file extensions (where applicable) in the right column.

To add a new MIME type, click the Add button. In the Configure MIME Type dialog, enter the new content type in the MIME Type field. If the new type has a corresponding file extension, enter this extension in the Extension field. Click the OK button when finished.

Similarly, you can edit or delete existing types using the Edit and Delete buttons.
