Wich version of Apache works with Tomcat 4.0.5, 4.06, and 4.1.2

[Carlos]

Hello Forum,
We are using IBM jdk1.3 in a Linux RedHat server, Apache 1.3.20-16, and
Tomcat 4.0.4 and 4.0.4.  Everything works fine.  Since we are planning on
upgrading the version of Tomcat, should we also upgrade the version of
Apache?

Thanks in advance for your response.
