whether or not to send the upload request to the external DLP system for scanning.
Once the Web Proxy receives the upload request headers, it has all the information necessary
to decide if the request should go to the external DLP system for scanning. The DLP system
scans the request and returns a verdict to the Web Proxy, either block or monitor (evaluate the
request against the Access Policies). The block page provided by the DLP system is shown to
the end user, if applicable.

Note — If any Data Security Policy group applies to the upload request, the Web Proxy
evaluates the policy group’s control settings against the upload request at the same time the
external DLP system scans the request. If a Data Security Policy setting blocks the request
before the DLP system is done scanning, the Web Proxy blocks the request and terminates the
ICAP session with the DLP system.
