Direct requests based on hashed cookie data
I have a requirement to pull a numerical value from a cookie and direct the request to one of 12 pools based on the hashed value of that cookie data. For example, a client's cookie contains 62. Divi...
What does your cookie data look like? Any particular reason you're using floor and divides instead of modular division? (The % operator.)
We don't allow floating-point in iRules, since tmm is essentially the kernel. However, you should be able to use a simple modular division to accomplish what you need. If the contents of the cookie isn't evenly entropic enough, you could always CRC32/MD5/SHA1 it and then perform your modular division on the hashed/digested value.
