## Incluir el mismo router múltiples veces con diferentes `prefix`

También puedes usar `.include_router()` múltiples veces con el *mismo* router usando diferentes prefijos.

Esto podría ser útil, por ejemplo, para exponer la misma API bajo diferentes prefijos, por ejemplo, `/api/v1` y `/api/latest`.

					}
					prefixes = append(prefixes, prefix)
				}
				if len(prefixes) > 0 {
					objInfo, _ := z.GetObjectInfo(ctx, bucket, pathJoin(opts.Prefix, "_SUCCESS"), ObjectOptions{NoLock: true})
					if objInfo.IsLatest && objInfo.DeleteMarker {
						return loi, nil
					}
				}
				li.Prefixes = prefixes
			}
			return li, nil
		}
	}

    /** Prefix used to identify role-based permissions */
    protected String rolePrefix = "{role}";

    /** Prefix used to identify group-based permissions */
    protected String groupPrefix = "{group}";

    /** Prefix used to identify user-based permissions */
    protected String userPrefix = "{user}";

    /** Prefix used to identify allow permissions */

	// When a prefix is provided in the request, The result contains only keys
	// starting with the specified prefix.
	Prefix string

	// A character used to truncate the object prefixes.
	// NOTE: only supported delimiter is '/'.
	Delimiter string

	// CommonPrefixes contains all (if there are any) keys between Prefix and the
	// next occurrence of the string specified by delimiter.

			continue
		}
		if strings.HasPrefix(objName, prefix) {
			if count == maxKeys {
				isTruncated = true
				break
			}
			if delimiter != "" {
				i := strings.Index(objName[len(prefix):], delimiter)
				if i >= 0 {
					commonPrefix := objName[:len(prefix)+i+1]
					if len(listObjectsInfo.Prefixes) == 0 || commonPrefix != listObjectsInfo.Prefixes[len(listObjectsInfo.Prefixes)-1] {

When Bucket Versioning with excluded prefixes are configured objects matching these prefixes are excluded from being versioned and replicated.

```
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
        <Status>Enabled</Status>
        <ExcludeFolders>true</ExcludeFolders>

        <ExcludedPrefixes>
          <Prefix>app1-jobs/*/_temporary/</Prefix>
        </ExcludedPrefixes>

You can also use `.include_router()` multiple times with the *same* router using different prefixes.

## Sobre proxies con un prefijo de path eliminado

Ten en cuenta que un proxy con prefijo de path eliminado es solo una de las formas de configurarlo.

Probablemente en muchos casos, el valor predeterminado será que el proxy no tenga un prefijo de path eliminado.
