     * <p>This method is called during model building for various model objects.
     * Implementations can:</p>
     * <ul>
     *   <li>Return the same object if no processing is desired</li>
     *   <li>Return a pooled equivalent object to reduce memory usage</li>
     *   <li>Return a modified or optimized version of the object</li>

# Automatic Site Replication

This feature allows multiple independent MinIO sites (or clusters) that are using the same external IDentity Provider (IDP) to be configured as replicas. In this situation the set of replica sites are referred to as peer sites or just sites. When site-replication is enabled on a set of sites, the following changes are replicated to all other sites:

- Creation and deletion of buckets and objects

     * repositories that were added first should also be searched first. When multiple repositories with the same
     * identifier are added, then the value of the replace argument determines the behaviour.
     *
     * If replace is false, then any existing repository with the same ID will remain in use. If replace
     * is true, the new repository replaces the original.

And all of them will use the same WebSocket connection.

## Using `Depends` and others { #using-depends-and-others }

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

They work the same way as for other FastAPI endpoints/*path operations*:

/// note

Previously, it was recommended to use `WSGIMiddleware` from `fastapi.middleware.wsgi`, but it is now deprecated.

It’s advised to use the `a2wsgi` package instead. The usage remains the same.

Just ensure that you have the `a2wsgi` package installed and import `WSGIMiddleware` correctly from `a2wsgi`.
