Chapter 38 URL Filtering
URL Filtering Window
Maximum Buffered HTTP Requests
You can set the maximum number of outstanding HTTP requests that the router
can buffer. By default, the router buffers up to 1000 requests. You can specify
from 1 to 2147483647 requests.
Maximum Buffered HTTP Responses
You can set the number of HTTP responses from the URL filtering server that the
router can buffer. After this number is reached, the router drops additional
responses. The default value is 200. You can set a value from 0 to 20000.
Advanced
The Advanced box allows you to choose the source interface. Choose the interface
from the Source Interface list.
Local URL List
If the Cisco IOS image on the router supports URL filtering but does not support
Zone-based Policy Firewall (ZPF), you can maintain one local URL list on the
router. This list is used by all Application Security policies in which URL filtering
is enabled. Cisco IOS images of release 12.4(9)T and later support all the ZPF
features that SDM supports. In a ZPF configuration, a local URL list can be
created for each URL filtering parameter map.
You can use Cisco SDM to create list entries and you can import entries from a
list stored on your PC. When a local URL list is used in combination with URL
filter servers, local entries are used first. See URL Filtering Precedence for more
information.
Maintaining the Local URL List
You can use Cisco SDM to maintain a local URL list by adding and deleting
entries one-by-one, and by importing a URL list from your PC and specifying
what you want Cisco SDM to do with each entry. Use the Add and the Delete
buttons to manage specific entries in the list on the router, and click the Import
URL List button to import a URL list from your PC.
