Traffic Shaping

Objects larger than the Maximum cached object size in memory (KB) are not kept in the memory
5
cache. This should be set high enough to keep objects accessed frequently in memory to improve
performance whilst low enough to keep larger objects from hoarding cache memory.
• Default: 32
• Integer value
[Optional] To enable the Web cache and access controls operate transparently, select the Transparent
6
proxy checkbox. Transparent operation filters and caches Web traffic regardless of whether or not the
clients on the LAN have specified an HTTP proxy in their Web browsers.
[Optional] To allow the Web cache to operate simultaneously with access controls, including content
7
filtering and antivirus, select the Interoperate with Access Controls and Antivirus checkbox.
Note: Due to limitations in peering proxies in this manner, user-based access controls will not work.
Select a level from the Anonymity Level list. The list controls the amount of identifying information
8
removed from Web requests in order to protect your anonymity. The levels of protection are specified in
increasing order and all but the first violate the HTTP standard and thus might cause problems with some
Web sites. Available options are:
• None: (default). No anonymity and no identifying information is removed from Web requests.
• Basic
• Paranoid
• Custom – The Custom setting is for users who have manually edited these settings in the cache
configuration file as it leaves the settings untouched.
Enter the maximum size of each log file before it gets rotated in the Log File Size (KB) field. If set to 0
9
(zero), the log files are rotated every time they are checked.
Default: 256
Specify how often the logs are checked for rotation in the Log File Rotation Time (minutes) field.
10
Default: 10
Specify how many log file rotations to store in the Log File Rotations field. The minimum default of 1
11
means 2 files are kept: the current log file and the previous log file. A maximum of 9 means 10 files are
kept.
• Default: 1
• Range: 1-9

Traffic Shaping
QoS (Quality of Service) traffic shaping is an advanced feature provided for expert users to fine-tune their
network connections. Traffic shaping allows you to give preference to certain types of network traffic to
maintain quality of service when a network connection is under heavy load.
Note: There must be only one LAN and one WAN in order to configure traffic shaping. At this time, traffic shaping
is not supported for configurations that include multiple LANs and DMZs. For the SG565 model, the wireless
connection must be unconfigured.
