Option Definition
Remove partial content for HTTP requests

When selected, a rule is enabled that removes the specification in an HTTP or HTTPS request for accessing only a part of the content of a web object and lets the request ask for the complete content.

If a web object, for example, a file, is delivered completely by the web server in question, it can also be scanned completely on Web Gateway. A complete scan can detect infections that might not be noticed if only a part of the web object was scanned.

Block partial content for FTP requests

When selected, a rule is enabled that blocks FTP requests for access to only a part of the content of a web object.

Under the FTP protocol. it is not possible to remove a specification in a request for access to only a part of the content of a web object. For this reason it might be advisable to block such requests.

Use the Media Stream Scanner

When selected, the Media Stream Scanner scans and delivers web objects that are streaming media chunk-by-chunk, to speed up the process.

The proactive functions of the McAfee Gateway Anti-Malware engine are used for the scanning, but the other engines that are available for this purpose on Web Gateway are not involved.
