Internal Website BIG-IP LTM Compatibility Issue

Hello F5 Community - I'm hoping to pick your big brains about troubleshooting an issue I'm having with the BIG-IP LTM. Forgive my ignorance, as I have not taken any of the F5 courses on the subject...

It has to do with the way files are chunked when downloaded, and most web-based applications don't really account for this in the standard manner.

Workaround: In the HTTP profile for that virtual server, change 

Response Chunking
to 
Rechunk
and try again.

I think the next step is two-fold. 1) Set the logging level to debug and watch for any related messages to that VIP. The most common is a RFC2616 error, which is where the HTTP is non-standard and rejected by the F5. 2) Use a program like Fiddler or HttpWatch to monitor the client session and capture the headers regarding the link generated by the PDF and the call to the PDF itself--see if it's experiencing unexpected behavior (like calling the name of the server directly).
