Note
If you do not include a protocol in the URL, 
http://
 will be prepended to it (e.g., 
www.cisco.com
 will become 
http://www.cisco.com
)
Specifying Domains or URLs that the Web Proxy never Caches
Step 1
Access the CLI.
Step 2
Use the 
webcache 
-> 
ignore 
commands to access the required submenus:
example.com> webcache
Choose the operation you want to perform:
- EVICT - Remove URL from the cache
- DESCRIBE - Describe URL cache status
- IGNORE - Configure domains and URLs never to be cached
[]> ignore
Choose the operation you want to perform:
- DOMAINS - Manage domains
- URLS - Manage urls
[]>
Step 3
Enter the address type you wish to manage: 
DOMAINS
 or 
URLS.
[]> urls
Manage url entries:
Choose the operation you want to perform:
- DELETE - Delete entries
- ADD - Add new entries
- LIST - List entries
[]>
Step 4
Enter add to add new entries:
[]> add
Enter new url values; one on each line; an empty line to finish
[]>
Step 5
Enter domains or URLs, one per line; for example:
Enter new url values; one on each line; an empty line to finish
[]> www.example1.com
Enter new url values; one on each line; an empty line to finish
[]>
You can include certain regular expression (regex) characters when specifying a domain or URLs. With 
the 
DOMAINS
 option, you can use a preceding dot character to exempt an entire domain and its subdomains 
from caching. For example, you can enter 
.google.com
 rather than simply 
google.com
 to exempt 
www.google.com, docs.google.com, and so on.
With the 
URLS
 option, you can use the full suite of regular-expression characters. See 
 for more information about using regular expressions.
