Yes. A Valve can be nested inside a Engine, Host, Context or Wrapper. (You won't see Wrapper in server.xml - it represents a Servlet) So something like: <Host ... > <Valve className="... /> ... </Host> should work for you use case. > I don't quite get the Java regex syntax, but I'm sure that my colleague > responsible for the webapp can help me there. > > My real problem is that I haven't the slightest idea what the health > check requests are specifying as user agent, or how to determine that, > and they appear to be coming from at least three different IP addresses. > I looked in the session list from the Manager, and I looked at > catalina.out, localhost....log, and localhost_access_log....txt, and > while I found the apparent IP addresses, I saw nothing that appeared to > identify a user agent. That won't matter. > Incidentally, what's the relationship between the "crawlerIps" and > "crawlerUserAgents" attributes? Is it an "or" or an "and"? It is an "OR" so you can leave crawlerUserAgents as the default and just set crawlerIps. If the IPs were 127.0.0.1 and 127.0.0.2 then I think you want crawlerIps="127\.0\.0\.1|127\.0\.0\.2" HTH, Mark --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
