How to set request header size for jetty

[Andreas Müller]

Hi,

the Jetty as bundled with jenkins cannot deal with headers larger than 8kB, but Jetty
can be configured to deal with larger headers, there is a setRequestHeaderSize() method
to the org.eclipse.jetty.server.HttpConfiguration class for this purpose. But what is the
accepted method to configure this for the Jetty in jenkins.war?

Best regards

HI Andreas,

were you able to resolve this issue? We have Jenkins installed on Linux using the RPM and need to increase the header size to get our SSO operational. What configuration file and parameter did you update to resolve the issue?

Error Currently encountered:

Please try this:

https://issues.jenkins-ci.org/browse/JENKINS-26963

workaround this by adding -Dorg.eclipse.jetty.server.Request.maxFormContentSize=500000 in the <arguments> XML node of <some_path>Jenkins\jenkins.xml

I added such options in jenkins.xml and it is resolved issue:

  <arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -Dorg.eclipse.jetty.server.HttpConfiguration.requestHeaderSize=32768 -Dorg.eclipse.jetty.server.HttpConfiguration.responseHeaderSize=32768 -Dorg.eclipse.jetty.server.Request.maxFormContentSize=500000 -jar "%BASE%\jenkins.war" --httpPort=8080 --requestHeaderSize=32768 --webroot="%BASE%\war"</arguments>
