The last sentence of the second paragraph of the section titled "General Tips on Running SSL" contains a typo: "... take the appropriate action *of* https is not specified." should read "... take the appropriate action *if* https is not specified." (The emphasis is mine.) The same typo occurs in the Tomcat 4.0 docs (the sentences are exactly the same). Hence, this report is relevant to http://jakarta.apache.org/tomcat/tomcat-4.0-doc/ssl-howto.html as well.
Fixed for 5.0 and 5.5. Thanks for reporting this issue.
