Many of you are very familiar with iRules, our Tool Command Language (Tcl) based scripter. It’s a powerful application delivery tool to have a programmable proxy that allows you to manipulate – in real time – any network traffic passing through the BIG-IP. Many BIG-IP fans have used it to address their specific needs and some iRules have even been productized as features. For example, the cool ASM Data Mask feature that blocks sensitive info like SSN or credit card numbers from leaking out was once an iRule. Aw, our baby made it to the BIGs.
