This avoids the issues of multiple versions of a class within a webapp, but the version the parent/system loader provides must be the right version for all webapps you configure in this way.

===== Configuring Webapp Classloader Caching
Introduced in Jetty 9.3.6, the link:{JDURL}/org/eclipse/jetty/webapp/CachingWebAppClassLoader.html[CachingWebAppClassLoader] can be used to cache `getResource(String)` results.
For webapps that search for classes and resources regularly, this can increase speed and performance.
This is an optional feature and it should be noted that it can conflict with several other libraries such as JSP, JSTL, JSF and CDI.
As such, this feature must be manually enabled for each webapp you want to use it in.
Below is an example of implementing this feature using Jetty IoC XML format:
[source, xml, options="header"]
----
<Configure id="mywebapp" class="org.eclipse.jetty.webapp.WebAppContext">
...
<Set name="classLoader">
<New class="org.eclipse.jetty.webapp.CachingWebAppClassLoader">
<Arg><Ref refid="mywebapp"/></Arg>
</New>
</Set>
...
</Configure>
