logged traffic, see "Querying Logs and Generating Reports" on page
default, HTTP traffic is not logged.

Select the checkbox to enable file extension blocking. By default, the File
Extension field lists the most common file extensions that will be detected. You can
manually add or delete extensions. Use commas to separate different extensions.
To narrow down the extensions to specific categories only, first delete the
extensions from the File Extension field, and then make a selection from the pull-
down menu:
• None. The most common file extensions are listed without being narrowed down
to a category. This is the default setting.
• Executables. The File Extension field lists executable file extensions.
• Audio/Video. The File Extension field lists audio and video file extensions.
• Compressed Files. The File Extension field lists compressed file extensions.
All embedded objects such as ActiveX, Java, and Flash objects are removed from
downloaded Web pages.
Note: Because embedded objects are commonly used on legitimate Web sites,
blocking embedded objects globally might have a negative impact on a user's Web
browsing experience.
