If you choose to not use the <IfModule>, you can instead directly place the WebLogic
properties inside Location or <VirtualHost> blocks.
Consider the following examples of the <Location> and <VirtualHost> blocks:
<Location /weblogic>
WLSRequest On
WebLogicHost myweblogic.server.com
WebLogicPort 7001
</Location>
<Location /weblogic>
WLSRequest On
WebLogicCluster w1s1.com:7001,w1s2.com:7001,w1s3.com:7001
</Location>
<VirtualHost apachehost:80>
WLSRequest On
WebLogicServer weblogic.server.com
WebLogicPort 7001
</VirtualHost>
