Accelerating Traffic with a Local Traffic Policy

About classifying types of HTTP traffic with a local traffic policy

An application that runs on a virtual server accelerates all HTTP traffic. You can, however, use a local traffic policy to classify types of HTTP traffic for the BIG-IP® system to accelerate, by specifying hosts, paths, headers, and cookies.

Important: Although you can use a local traffic policy to classify the types of HTTP traffic to accelerate, the local traffic policy overrides the Web Acceleration profile on the virtual server. Acceleration of HTTP traffic with the BIG-IP system should primarily be configured through a Web Acceleration profile, instead of a local traffic policy.

Local traffic policy matching Strategies settings

This table summarizes the strategies used for traffic policy matching.

Matching strategy Description
First-match strategy A first-match strategy executes the actions for the first rule in the Rules list that matches.
Best-match strategy A best-match strategy selects and executes the actions of the rule in the Rules list with the best match, as determined by the following factors.
  • The number of conditions and operands that match the rule.
  • The length of the matched value for the rule.
  • The priority of the operands for the rule.
Note: In a best-match strategy, when multiple rules match and specify an action, conflicting or otherwise, only the action of the best-match rule is executed. A best-match rule can be the lowest ordinal, the highest priority, or the first rule that matches in the Rules list.
All-match strategy An all-match strategy executes the actions for all rules in the Rules list that match.
Note: In an all-match strategy, when multiple rules match, but specify conflicting actions, only the action of the best-match rule is executed. A best-match rule can be the lowest ordinal, the highest priority, or the first rule that matches in the Rules list.

Local traffic policy matching Requires profile settings

This table summarizes the profile settings that are required for local traffic policy matching.

Requires Setting Description
http Specifies that the policy matching requires an HTTP profile.
ssl Specifies that the policy matching requires a Client SSL profile.
tcp Specifies that the policy matching requires a TCP profile.

Local traffic policy matching Controls settings

This table summarizes the controls settings that are required for local traffic policy matching.

Controls Setting Description
acceleration Provides controls associated with acceleration functionality.
caching Provides controls associated with caching functionality.
classification Provides controls associated with classification.
compression Provides controls associated with HTTP compression.
forwarding Provides controls associated with forwarding functionality.
persistence Provides controls associated with persistence functionality.
request-adaptation Provides controls associated with request-adaptation functionality.
response-adaptation Provides controls associated with response-adaptation functionality.
server-ssl Provides controls associated with server-ssl functionality.
