For example, there's an official <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python Image</a>.

Guava comes in two flavors:

*   The JRE flavor requires JDK 1.8 or higher.
*   If you need support for Android, use

 * application data - do we need a dictionary for our applications like Apple does. We could easily
 * hook into this and this is the model we need to follow - how many of our REST services do not map
 * directory to a method in the application interface?
 *
 * - research extension points versus plugins
 *

        // Add many parameters
        for (int i = 0; i < 100; i++) {
            request.param("param" + i, "value" + i);
        }

        assertNotNull(request);
    }

    @Test
    public void testManyHeaders() {
        CurlRequest request = new CurlRequest(Method.GET, "https://example.com");

        // Add many headers
        for (int i = 0; i < 50; i++) {

And your **FastAPI** application with WebSockets will respond back:

You can send (and receive) many messages:

And all of them will use the same WebSocket connection.
