Jetty limits the amount of data that can post back from a browser or other client to the server. This helps protect the server against denial of service attacks by malicious clients sending huge amounts of data. The default maximum size Jetty permits is 200000 bytes. You can change this default for a particular webapp, for all webapps on a particular Server instance, or all webapps within the same JVM.
The method to invoke is: ContextHandler.setMaxFormContentSize(int maxSize);
This can be done either in a context XML deployment descriptor external to the webapp, or in a jetty-web.xml
file in the webapp’s WEB-INF
directory.
In either case the syntax of the XML file is the same:
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<!-- Max Form Size -->
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<Set name="maxFormContentSize">200000</Set>
</Configure>
Set an attribute on the Server instance for which you want to modify the maximum form content size:
<Configure class="org.eclipse.jetty.server.Server">
<Call name="setAttribute">
<Arg>org.eclipse.jetty.server.Request.maxFormContentSize</Arg>
<Arg>200000</Arg>
</Call>
</Configure>
