Icap Option: Specify Icap Server Settings - M86 Security M86 Web Filter User Manual

NOTES: The Current MAC Address displays if there is a resolu-
tion between the IP address and the MAC address of the router
or device used for serving block pages.
If an Alternate IP Address is used, that address must be resolved
with the MAC address in order for block pages to be served to
client PCs.

ICAP Option: Specify ICAP Server Settings

The ICAP Server Settings frame displays if the ICAP opera-
tion mode is selected. This option should be used if this
Web Filter is designated to function with an Internet Content
Adaptation Protocol (ICAP) server to off-load specific
content normally processed by the Web Filter, such as
Internet filtering.
With an ICAP server, the Web Filter will not capture any
network packets but will solely work with ICAP requests
from an ICAP client (proxy server). When an end user
makes a request for Internet content, this request is routed
to the proxy server, which then submits the request to the
ICAP server. The ICAP server sends back a response to the
proxy server—which may send the request to the original
Web Filter in some network setups, and then return a
response to the proxy server. Based on the end user's
filtering profile, the proxy server either fulfills the request or
returns a block page.
The ICAP Server Settings frame is used for configuring
options response settings for the ICAP Web Filter server:
1. In the ISTAG field, enter the ISTag (ICAP Service Tag)
M86 S U G
ECURITY SER UIDE
G
LOBAL
which is a 128-maximum alphanumeric quoted string of
data (including quotation marks but never the null char-
acter) used in the options response-header field. This tag
provides a way for ICAP servers to send a service-
specific "cookie" to ICAP clients so that the ICAP server
can communicate with the ICAP client. For example:
