Therefore, using this for large payloads will likely be slower than using a separate connection,
and other connections will be blocked while the large payload is being sent.

## Handlers & Routes

Handlers have a predefined Handler ID. 
In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.

// or network connections.
//
// A Profile's methods can be called from multiple goroutines simultaneously.
//
// Each Profile has a unique name. A few profiles are predefined:
//
//	goroutine    - stack traces of all current goroutines
//	heap         - a sampling of memory allocations of live objects
//	allocs       - a sampling of all past memory allocations

## Deployment Concepts

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

This is the basic idea. But you will probably want to take care of some additional things, like:

* Security - HTTPS
* Running on startup
* Restarts

During execution functions are found in two function maps: first in the
template, then in the global function map. By default, no functions are defined
in the template but the Funcs method can be used to add them.

Predefined global functions are named as follows.

	and
		Returns the boolean AND of its arguments by returning the
		first empty argument or the last argument. That is,
		"and x y" behaves as "if x then y else x."
