+### Zero Allocation
+Some values returned from \***fiber.Ctx** are **not** immutable by default.
 
 Because fiber is optimized for **high-performance**, values returned from **fiber.Ctx** are **not** immutable by default and **will** be re-used across requests. As a rule of thumb, you **must** only use context values within the handler, and you **must not** keep any references. As soon as you return from the handler, any values you have obtained from the context will be re-used in future requests and will change below your feet. Here is an example:
