You could use JMX to update the list of denied IP addresses. Better yet, just use iptables. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Denying IP Addresses
Hi all, Just soliciting some feedback on how to effectively, thwart data mining on our server. We have a reactive solution when it comes to screen scraping and data mining on Tomcat 5.5. We simply find the offending IP's and add them to the deny rules using the Valve - org.apache.catalina.valves.RemoteAddrValve >From what I understand, for changes to take effect, requires a restart of Tomcat. I was thinking to override the RemoteAddrValve to retrieve offending IP's from a file as well, so as not requiring a restart everytime an offending IP is found. Our applications then would be able to identify offending IP's, and based on their own rules, add them to the file. Is this a viable strategy? Thanks in advance, Ed
