<![CDATA[Change default header size for Mango Webserver]]>Hello,
Our mango UI instance is riddled with "431 (Request Header Fields Too Large)" errors in our Chrome browser console. We constantly have to clear our cache in order for the UI to load properly.

My company uses an in-house, custom proxy service that injects several large headers of its owns, which is potentially the culprit. The team's suggestion was to update the maximum HTTP header size limit in our Mango Web Server config.

How can I increase this in our Mango server to 32kb or 64kb to see if this resolves our issue? Poking around online, Jetty stores the value "requestHeaderSize" in jetty.xml and defaults to 8192 bytes.
