// The responses for fetching the object when If-Modified-Since

// If-Modified-Since - Return the object only if it has been modified since the specified time, else return a 304 (not modified).
// If-Unmodified-Since - Return the object only if it has not been modified since the specified time, else return a 412 (precondition failed).

Before OpenAPI 3.1.0, OpenAPI used an older and modified version of **JSON Schema**.

JSON Schema didn't have `examples`, so OpenAPI added its own `example` field to its own modified version.

OpenAPI also added `example` and `examples` fields to other parts of the specification:

    /**
     * Set the last modified time of the file. The time is specified as milliseconds
     * from Jan 1, 1970 which is the same as that which is returned by the
     * <code>lastModified()</code> method.
     * <br>
     * This method does not apply to workgroups, servers, or shares.
     *
     * @param time
     *            the last modified time as milliseconds since Jan 1, 1970

  /*
   * Per JDK: "the behavior of a map entry is undefined if the backing map has been modified after
   * the entry was returned by the iterator, except through the setValue operation on the map entry"
   * As such, this field must be cleared before every map mutation.

* **`300 - 399`** "Перенаправлення". Відповіді з цими кодами можуть мати або не мати тіла, за винятком `304`, "Not Modified" (не змінено), яка не повинна мати тіла.
* **`400 - 499`** "Помилка клієнта". Це другий тип, який Ви, ймовірно, будете використовувати найчастіше.

- On Kubernetes setups, the statefulset specification needs to be modified by changing the command line input for the MinIO container. Once the relevant changes are done, proceed to execute `kubectl apply -f statefulset.yaml`.

        FileNotifyInformation modifiedFile = mock(FileNotifyInformation.class);
        when(modifiedFile.getAction()).thenReturn(FileNotifyInformation.FILE_ACTION_MODIFIED);
        when(modifiedFile.getFileName()).thenReturn("modified.txt");

        FileNotifyInformation renamedOld = mock(FileNotifyInformation.class);
        when(renamedOld.getAction()).thenReturn(FileNotifyInformation.FILE_ACTION_RENAMED_OLD_NAME);

Some requests will have a cached response. When this cached response isn’t fresh, OkHttp can do a _conditional GET_ to download an updated response if it’s newer than what’s cached. This requires headers like `If-Modified-Since` and `If-None-Match` to be added.
