I'll keep your notes and if I get some energy I'll see. We've been 
fighting with this for 2 weeks and both the IT person and I just want it 
to go away. There are currently thousands of users actively working with 
the software so I'm hesitant to do anything much to it. Right now we 
have a working production server using Passenger 3 (works fine) and a 
staging server where we're trying to get Passenger 5 to work for some 
other reasons.

To be honest, you've been more help than anyone else, for which I'm 
really grateful. She originally contacted the Passenger forum and they 
had little to offer outside of "your app should be handling the 
chunking. Not our problem." And then they locked the thread. So we 
tinkered around with dozens of things for days without any luck.

Yes, the server person is doing that now in her script. Apparently if 
Passenger sees that header it doesn't add any of the others it otherwise 
tries to append.

I don't fully understand the data flow over there, but it seems to go 
from Rails to Passenger to Apache/AWS. And it sure looks to me like both 
Passenger and AWS are adding headers when they think it's necessary. We 
don't have much control over AWS but experimentation has shown us that 
we can shut up Passenger by including a content-length header ourselves.

I'm going to show her this thread and let her decide if she should 
report the issue to the Passenger people.
