Problem(Abstract) |
This technote provides information on the
OptimizeRuleMapping directive.
The minimum release levels that support this directive are: 4.0.2.58,
5.0.2.39, 5.1.1.18, 6.0.2.2.
If you configure a large number of mapping rules, Caching Proxy is slower
to start and the proxy performance decreases. When the number of rules in
the configuration is greater than 300, use the OptimizeRuleMapping
directive to increase performance. |

Resolving the
problem |
When you enable the OptimizeRuleMapping directive, instead
of mapping incoming URI requests against each rule one-by-one, the proxy
maps the URI against a prefix tree.
The prefix tree helps proxy remove the redundant string comparison among
the mapping rules. As a result, Caching Proxy achieves better performance
when the number of rules in your configuration is greater than 300.
Syntax:
OptimizeRuleMapping [on | off ]
Default: off |
