With at least two endpoints and Traffic Policy, you can run simple A/B tests using the rand.double() macro
Basic example This rule:
Uses rand.double() to generate a random double between 0 and 1 when traffic reaches the endpoint
Checks if the value is less than or equal to 0.5
If so, it routes the traffic to a different internal Agent Endpoint .
You can change the value the random number is checked against to split the traffic in different ratios.
For example, >=0.8 would send 80% of the traffic to one endpoint and 20% to the other.
See the forward-internal Traffic Policy action docs for more information.
Using rewrites You can also send the traffic to a different route using URL rewrites.
See the URL Rewrite Example for another example using rewrites.
