We here at DevCentral are the folks who work on the API (iControl) and the onboard packet inspector/scripting language (iRules). If you have a question about building iControl apps or writing iRules, this is the place for you.
Unfortunately, this isn't the place for product technical support. We simply aren't staffed to handle that side of things. You'll need to talk to the folks in our product support department for questions like these.
They can be easily contacted here:
