Andrew -
Thanks for this reply. I have solved the problem, though I am not
sure I have figured it out. Our institution allows us to set a flag on
login that warns us if we are moving to another application. I set the
flag for curiosity's sake and lo and behold, when I went to my file
upload servlet, CAS thought I was moving to another application.
In my HTML, the link I had to the servlet was an absolute link. I
changed it to a relative link and everything worked.
So this is what I assume was going on. If the link is not relative,
the CAS client assumes that you are moving to another application, and
forwards the request to the CAS server. Because
the CAS server is interposed, the contents of the request are lost.
Does this sound plausible? Is it correct behavior?

Thanks for raising this issue.
Please create a JIRA documenting the defect.
Is it convenient for you to produce a minimal noise example
demonstrating this problem? I'm thinking source that builds to a .war
that includes the file upload servlet, declares the CAS filter, and
maps the servlet behind and not behind the filter.
Not looking to create a bunch of work for you, but if you're in a
position to provide such an example (would be a fine addition to the
JIRA), Marvin and I are here at Jasig Dev Days through Friday and I
know for me that jump start to seeing the problem you're seeing would
appreciated.
Thanks,
Andrew

I have a webapp that uses CAS. In the part of my app that I want
filtered by CAS I have a file upload servlet.
When the HttpServletRequest arrives at the servlet the content type
is null and there are no parameters. If I move
the file upload outside of the CAS-filtered area, the
HttpServletRequest contains the proper content type and
parameters.
I am using CAS client 3.2.0.
