What is default value for http parameters MAX_COUNT wildfly?

We have upgraded jboss to wildfly , in older version we were facing some issue like this Maximum number of parameter passed in a post.

In older version of jboss we got this error message 

2015-02-10 20:04:34,582 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/sf].[action]] (http--

Now to verify this issue we wanted to know what is the default value for http parameters MAX_COUNT.

On googling i found this discussion where there is no much information provided, on how it is fixed http://lists.jboss.org/pipermail/undertow-dev/2013-April/000287.html

Solution

  • Default value of max parameter count is "1000", if you want to modify it

    In wildfly we have to use "max-parameters" attribute in http-listener.

    <http-listener name="default" socket-binding="http" max-parameters="10000"/>

    For documentation please refer here

    In 7.x version you can fix by below change

    org.apache.tomcat.util.http.Parameters.MAX_COUNT=10000

    For older version of jboss max parameter count discussed here
