HTTP Error 414. The request URL is too long.

[Seth Mayers]

I am running Apache Tomcat Version 9.0.48.

If I post a transaction that is very large, I get the "414; The request URL
is too long".

I have tried adding a bunch of parameters to my server.xml file but none of
them seem to work.  I have tried:
maxHttpHeaderSize="262144"
maxSavePostSize="-1"
maxPostSize="-1"
maxHttpRequestHeaderSize="262144"

I have someone that was able to resolve the same issue running Tomcat 8.5
but his solution (maxhttpheadersize) did not work for me.  Did something
change between 8.5 and 9.0.48 that might affect things?  Is
something involved beyond just server.xml?
