I currently am integrating Websense Enterprise for IOS into my infrastructure. The filtering is working normally but I find that outside of the exclusive domains I have configured there is no caching occurring. I did a debug and found out like this to be the norm:
May 26 13:37:40.008: URLF: creating uis 0x8269DD80, pending request 1
May 26 13:37:40.008: URLF: domain name not found in the exclusive list
May 26 13:37:40.008: URLF: got an cbac queue event...
May 26 13:37:40.008: URLF: websns making a lookup request.

May 26 13:37:40.068: URLF: got a socket read event...
May 26 13:37:40.068: URLF: socket recv (header) successfull.
May 26 13:37:40.068: URLF: socket recv (data) successfull.
May 26 13:37:40.068: URLF: websns lookup code = 0
May 26 13:37:40.076: URLF: websns lookup description code = 1026
May 26 13:37:40.076: URLF: websns category number = 153
May 26 13:37:40.076: URLF: websns cache command = 0
May 26 13:37:40.076: URLF: websns cached entry type = 0
May 26 13:37:40.076: URLF: Site/URL allowed: sis 0x81FB7600, uis 0x8269DD80
May 26 13:37:40.076: URLF: deleting uis 0x8269DD80, pending requests 0u all
In looking at this it seems that the Websense server is determining if the URL can be cached. The question I have is how the caching is determined, on the Websense server or the Router? How do I enable caching so that performance can be increased? I have a case open with Websense but they have not been forthcoming in answering this question. Any help would be appreciated.
