### HTTP Response { #http-response }

The application would process the request and send a **plain (unencrypted) HTTP response** to the TLS Termination Proxy.

        // Test process method without properties path
        ThumbnailGenerator.Options options = new ThumbnailGenerator.Options();
        options.numOfThreads = 2;
        options.cleanup = true;

        // Setup mock components
        setupMockComponents();

        Method processMethod = ThumbnailGenerator.class.getDeclaredMethod("process", ThumbnailGenerator.Options.class);

    int NT_STATUS_OBJECT_PATH_NOT_FOUND = 0xC000003a;
    /** The object path syntax is bad */
    int NT_STATUS_OBJECT_PATH_SYNTAX_BAD = 0xC000003b;
    /** The process cannot access the file because it is being used by another process */
    int NT_STATUS_SHARING_VIOLATION = 0xC0000043;
    /** The file is pending deletion */
    int NT_STATUS_DELETE_PENDING = 0xC0000056;

    }

    // Test that process method is abstract
    public void test_processMethodIsAbstract() throws Exception {
        try {
            java.lang.reflect.Method processMethod =
                    CorsHandler.class.getDeclaredMethod("process", String.class, ServletRequest.class, ServletResponse.class);

This is still true.

So, to be able to have **multiple processes** at the same time, there has to be a **single process listening on a port** that then transmits the communication to each worker process in some way.

### Memory per Process { #memory-per-process }

        assertTrue(result.contains("Python Process terminated."));
    }

    // Test execute with timeout
    public void test_execute_withTimeout() {
        pythonJob.filename("timeout.py");
        pythonJob.timeout = 60; // Set timeout
        pythonJob.processTimeout = true;

        testProcessHelper.exitValue = -1;
        testProcessHelper.processOutput = "Process terminated";

            if (logger.isDebugEnabled()) {
                logger.debug("Failed to process a scroll request.", e);
            }
            writeJsonResponse(HttpServletResponse.SC_BAD_REQUEST, e);
        } catch (final Exception e) {
            if (logger.isDebugEnabled()) {
                logger.debug("Failed to process a scroll request.", e);
            }

            restrictions.add(restriction);
            upperBound = restriction.getUpperBound();

            process = process.substring(index + 1).trim();

            if (process.startsWith(",")) {
                process = process.substring(1).trim();
            }
        }

        if (!process.isEmpty()) {
            if (!restrictions.isEmpty()) {
                throw new InvalidVersionSpecificationException(

                logger.warn("Failed to process {}", id, e);
            }
        } catch (final Exception e) {
            logger.warn("Failed to process {}", id, e);
        }
        return false;
    }

    /**
     * Processes thumbnail generation with a response data consumer.
     * @param id The document ID.
     * @param consumer The consumer function to process response data.

The only new option here is `--workers` telling Uvicorn to start 4 worker processes.

You can also see that it shows the **PID** of each process, `27365` for the parent process (this is the **process manager**) and one for each worker process: `27368`, `27369`, `27370`, and `27367`.
