How to configure the cache to handle the Vary Header ?

Make sure that the content being served is matching to the XML node in the WebAccelerator policy. XML pages should be matching to the XML node in the library policy. The default settings on this node is for WebAccelerator to not cache the content. If the default settings have been changed the variation rules need to be used to ensure that content is cached appropriately. In your example you would need to add a variation rule for the Accept header. The default is that all headers serve the same content and in this case the Accept:notice header needs to be defined to serve different content.

Select Variation rules

 

From the "Add Parameter" dropdown select Header

 

Click Add

 

In the Name box enter "Accept"
