It doesn't matter that you're using Catalyst for this problem.

Your first question should be whether SAP actually returns the data/MIME 
type as part of it's response to your request. If so crib it from there.

If not, you could save the binary data to a file and run some form of 
file-type/magic number detection. If you're running in a unix environment 
you might find the "file" command useful for this.
