About iRules

iRules, an exclusive application-fluent F5 technology, are customizable commands that leverage the power of F5's unique TMOS architecture. iRules help define how F5 products secure, optimize, and deliver any bi-directional IP application traffic or flow, giving customers complete and granular control over their application traffic. Based on the popular Tool Command Language (TCL) and F5-specific extensions, iRules enable enterprises, service providers, and e-businesses to offload costly application functions that previously had to be performed by the applications themselves. With so many distributed applications, this centralized functional capability saves customers a tremendous amount of development work and can ensure successful application implementations without having to change the network or the application.
