Forum: NGINX why two different responses?

One of these requests is sent by my program.  One is sent by curl (it's
easy to tell which).   They are identical as far as I can tell.
However, the curl request returns the expected result (204) from my
servlet.  The program keeps getting this 302 returned with some generic
"302 Found" html from nginx.

My eyes are blurry from staring at it.  Can anyone tell me why my test
with curl works, but the program sending the same request does not???

Thanks,
AJ

What is the full request sent in each case?

"curl -v" to show what it sends. Or "tcpdump" on the nginx server to
see what it receives.

If you see different headers sent from your code and curl, perhaps try
adding or removing one at a time to see if there is one that matters.

Purely on the lines you have shown: does your code or config do anything
based on $http_user_agent or the equivalent?

Most probably your program does not pass "Host" header.
