mark/reset exception when using HttpManager to send chunked messa ge

I am trying to send chunked data using the HttpManager and Request objects.
I am using a PipedInputStream / PipedOutputStream to supply and read the
data. It seems that all the data gets passed through the streams, but then I
get the mark/reset exception.  If PipedInputStream does not support
mark/reset, what other options are available?  Keep in mind that the chunked
data is very likely generated on the fly, not read from a static location.
