We are running ORDS in standalone mode (with self signed certificate for HTTPS), but the requests are coming from a sign-on service which injects some big cookies in the request header.
Thus in ORDS we are getting "Header is too large 8193>8192" and error 431 from Jetty.
There are solutions described for different Jetty configurations that involve standalone/etc/jetty-http.xml file and various contents in it.
Looking at the Jetty docs, we tried with the following in this file:
<Configure id="httpConfig" class="org.eclipse.jetty.server.HttpConfiguration">
Thus, trying to increase the value 4 times above the default for Jetty - 8kb. But that does not impact ORDS/Jetty behavior.
Actually we have tried solution for NCSA style logging and it works. Now we need to incorporate also a setting for increased header size.
