Blocking specific IP addresses with Tomcat

[Jiger Java <ji...@hotmail.com>]

Hi all,
       Does anyone know of a way to block users from specific IP Address(say 
in case of DDos Attacks or just limiting no. of request/IP).
I want to implement this on Tomcat either 3.x or tomcat 4.
I know it is possible using Apache but any idea how we can do this if tomcat 
is running in standalone mode.

Thanks,
Jiger

In Tomcat 4 you can use Request Filters for blocking, but by the time it
gets that far you've already invested nearly as much effort as it would
take to just go ahead and process the request.

Your best bet is to take advantage of the firewalling capabilities of your
operating system (most Linux variants come with quite nice packages for
managing this kind of thing, for example).
