Application Center Test (ACT) Request.ResponseBufferSize - Binary Data

[benh]

Does anyone have any insight into how Application Center Test handles
binary data in a response body?

My problem:
I need some specific data from inside a PDF file that is coming down
as the response body. The response contains binary data mixed with
plain text which is where my data lies. Unfortunately, when I print
the response body to the Trace Log it is truncated. The response
ContentLength is about 21,000 bytes so I have used
Request.ResponseBufferSize to set the buffer to 70,000 bytes but the
data is still truncated right where the binary data begins.

Also, I don't know if it matters but I notice the response Code Page
is 65001 (CP_UTF8) which is listed in ACT help as a supported code
page.

Does anyone have any idea why the response is truncating at the
beginning of binary data or how I can tell ACT not to do this??

Thanks in advance!
