When troubleshooting, you often follow this standard practice:
1. Clear statistics.
2. Reproduce a problem.
3. View statistics.
To clear filtering statistics, enter this enable mode command:
ProCurve# clear ip urlfilter statistics
For more detailed troubleshooting, you can view all event messages related
to Web content filtering. Enter this enable mode command:
ProCurve# debug ip urlfilter
The command line interface (CLI) then displays events such as:
the ProCurve Secure Router connecting to a Websense server
the router sending a request to check whether an HTTP request to a
particular URL is allowed
the router receiving responses from Web servers
the router receiving a response from a Websense server and either allow-
ing or blocking a URL
a connection with a Websense server timing out
the router applying an exclusive domain rule
the router dropping traffic from a Web server because the maximum
number of buffered responses has been reached
Table 7-2 shows some debug messages and the problems that they may
