Hey, What does these streams are? in a http level a stream can be cached unless it's an *unranged* stream which is like a one way stream with no end.. or with 100 continue parts that has no actual limit in the request. If you do have some access.log for an example and a link for this kind of source we might be able to tell you if it's cachable.
