Filter Class Name: atg.portal.servlet.DeviceFilter
The Device Filter creates and initializes the Portal request’s DEVICE attribute. The mimeTypes property is derived from the HTTP accept header. The preferred MIME type is determined by matching the Device Filter’s mimeTypePreferences parameter to one of the accept headers, using a regular expression.
For example, if the mimeTypePreferences parameter in the Device Filter is set to:
text/html
text/vnd.wap.wml
text/xml
And the request contains the following accept headers:
text/*
image/jpeg
image/png
image/*
*/*
then the preferred MIME type will be text/html.
The following attribute is set when the filter is invoked.
