CF: ColdFusion Impact of Content Type Declaration on the HTTP header with application/octet-stream

So, I encountered this little problem with XML transmissions for a customer. They would receive regular XML streams to update their data and all was working dandy, until one it didn't ;o)
To CF it looked like all of a sudden the content of the HTTP traffic vanished, in other words we did not seem to have anything in GetHttpRequestData().content except for empty string.
Of course, no one fessed up to having changed anything at all, so here I go digging through code and cannot find anything obvious and, then, I turn out the big guns: Protocol Sniffers and packet capture.
Hah, I think, now I can show them that they are not sending any content, but instead I can see the content clearly in the packet capture which starts heavy head scratching and coffee sipping.
More looking into code and I find that the only time we bypass GetHttpRequestData().content is if we are running a binary check, e.g. we have this condition:
IsBinary(GetHttpRequestData().content)
From the protocol packets I can clearly see that the content is not binary so, at first, I cannot imagine how this condition would be even trigger and bypass the remainder of the processing until, seing the light, I remove the condition.
Bingo, now I can see content but it is all wrong. It looks like CF has processed the content of the transmission to numeric values instead of XML strings.
Dang!
So in the end, more digging to see that the http content type declaration of the originating transmission had changed from text/xml to application/octet-stream; it looks like whenever CF received this it automatically converted the perfectly fine XML into an octet stream, which, then, turned the content to be binary data instead of leaving it as simple string. A simple misdeclaration by the customer which caused this hoopla.
So after much searching I wish I could have been able to tell the RAW data in the transmission from the interpreted data. This would have made the diagnosis much simpler. So Adobe, in the future please consider adding the raw information to the GetHttpRequestData function, so we don’t have to guess what parts are being interpreted and what the transmission contained.
For now, I went back to the customer and asked them to correct their content declaration.
