Flushing Existing Cached Content from the Appliance Parent topic

There is a potential risk of infection from content cached to the Blue Coat Port 80 Security Appliance or the Cisco ICAP servers before IWSVA ICAP started scanning HTTP traffic.
To safeguard against this possibility, Trend Micro recommends flushing the cache immediately after configuring IWSVA ICAP. All new requests for Web content are then served from the Internet and scanned by IWSVA ICAP before caching. Scanned content is then cached on the Blue Coat Port 80 Security Appliance or the Cisco ICAP servers. The the Blue Coat Port 80 Security Appliance or the Cisco ICAP servers serve future requests for the same Web content by your network users. Because the request is not sent to the Internet, download time is accelerated.
Flush the existing cached content in the applicable appliance as follows:
To flush the cache in the Blue Coat Port 80 Security Appliance:
  1. Select Management.
  2. Type the logon user name and password if prompted.
  3. Click Maintenance.
  4. Click Tasks and click Clear. Click OK to confirm.
To flush the cache in the Cisco ICAP server:
  1. Telnet to Cisco CE.
  2. At the root CLI menu, type cache clear.
  3. Press Enter.
