Example
MIME Type Header-Based Redirection
In this example, Alteon receives a URL request from a mobile client and examines the Multipurpose
Internet Mail Extensions (MIME) type header in the URL. If the URL contains a pre-defined MIME
type, text, or URL, Alteon replaces the URL. Use the string index numbers to configure a redirection
map for the filter.

Filter 6—The mobile client executes a request for a URL http://dev.example.com/java/
toggle.jad. If the MIME type is text/vnd.foo.j2me.app-descriptor, or if the URL contains jad
or jar as an extension, it will replace the URL with:
http://mobile.example.com/4g/w?url=dev.example.com/nava/toggle.jad.
