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? -Eric Disclaimer : This email and any files transmitted with it are confidential and intended solely for intended recipients.
