Client Authentication
---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

		if claims.AccessKey != globalActiveCred.AccessKey {
			u, ok := globalIAMSys.GetUser(req.Context(), claims.AccessKey)
			if !ok {
				// Credentials will be invalid but for disabled
				// return a different error in such a scenario.
				if u.Credentials.Status == auth.AccountOff {
					return nil, errAccessKeyDisabled
				}
				return nil, errInvalidAccessKeyID
			}
			cred := u.Credentials
			// Expired credentials return error.

Network programming latency may be significantly reduced in certain scenarios, especially in clusters with a large number of Services.

In diesem Szenario der parallelen Hamburger sind Sie ein Computersystem / Programm 🤖 mit zwei Prozessoren (Sie und Ihr Schwarm), die beide warten 🕙 und ihre Aufmerksamkeit darauf verwenden, „lange Zeit vor der Theke zu warten“ 🕙.

In an advanced scenario where you know you need the dependency to be called at every step (possibly multiple times) in the same request instead of using the "cached" value, you can set the parameter `use_cache=False` when using `Depends`:

=== "Python 3.8+"

//
// Some types of a queries are not valid. For example, an aggregation
// function combined with a row function is meaningless ("AVG(s.Age) +
// s.Salary"). Analysis determines if such a scenario exists so an
// error can be returned.

var (
	// Fatal error for query processing.
	errNestedAggregation      = errors.New("Cannot nest aggregations")

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

```Python hl_lines="14"
{!../../../docs_src/handling_errors/tutorial002.py!}
```
