Web Gateway also provides functions, such as web caching or progress indication that do not themselves filter web objects, but support the filtering process in different ways.
- Web caching
- Progress indication
- File opening
- Bandwidth throttling
- Next-hop proxies
Functions supporting web filtering
Some of the functions that support web filtering are implemented by rule sets of the default rule set systems. Rule sets for other functions can be imported from the library.
The default rule sets for supporting functions are all embedded in the Common Rules rule set. Rule sets for web caching, progress indication, use of file openers, and other functions can be found here.
The library provides rule sets for bandwidth throttling and the use of next-hop proxies for web access.
