Can We Disable Chunked Encoding?
We've been seeing problems with failed requests where the response comes back with duplicate chunked encoding headers:
[Response]
HTTP/1.1 200
Strict-Transport-Security: max-age=86400; includeSubDomains;
Cache-Control: no-cache,no-store
isAuthenticated: true
X-FRAME-OPTIONS: SAMEORIGIN
Transfer-Encoding: chunked <<<<<<<<<<<<<
X-XSS-Protection: 1; mode=block
vary: accept-encoding
Content-Encoding: gzip
Content-Type: text/xml;charset=ISO-8859-1
Transfer-Encoding: chunked <<<<<<<<<<<<<< Duplicate
Date: Wed, 05 Jul 2023 17:22:11 GMT
This is a violation of RFC 7230, so our nginx proxy is dropping the request and returning a 502 bad gateway error. I've spoken to F5 about this, and there's no way to make nginx ignore this violation. Unfortunately, the app is a canned product, and we don't have access to the code.
Is there a way to disable that behavior in Tomcat?

Check the message source for headers identifying the thread.

My apologies. I wasn't aware that something else besides the subject line identifies a thread. I thought changing the subject line *IS* starting a new thread. Thanks for letting me know. For my own edification, what does the list look for in a message to identify the thread?

Please don't hijack threads by replying to a previous message and
changing the subject. Start a new thread by sending a new message to the
list.
You also need to provide some version information.
