Force a Page Refresh in Selenium to Prevent Cache‑Induced Slowdowns

While using Selenium for repetitive operations, the page may become sluggish due to caching, leading to timeout errors during data submission. A custom forced‑refresh approach solves this by programmatically sending a Ctrl+F5 key combination, which forces the browser to reload the page without using the cached version.

Refresh Utility Method

public static void refresh(WebDriver driver) {
    Actions ctrl = new Actions(driver);
    ctrl.keyDown(Keys.CONTROL).perform();
    try {
        pressKeyEvent(KeyEvent.VK_F5);
    } catch (AWTException e) {
        output(sad + getNow());
        e.printStackTrace();
    }
    ctrl.keyUp(Keys.CONTROL).perform();
    // driver.navigate().refresh();
}

This method creates an Actions instance, holds down the Control key, triggers the F5 key via a low‑level robot event, handles possible AWTException, and finally releases the Control key.

Low‑Level Key Event Helper

public static void pressKeyEvent(int keycode) throws AWTException {
    Robot robot = new Robot();
    // robot.keyPress(KeyEvent.VK_ENTER); // example for Enter key
    robot.keyPress(keycode);
}

The helper uses java.awt.Robot to simulate a physical key press, allowing any virtual‑key code (e.g., KeyEvent.VK_F5) to be sent to the operating system.

Important Import

import org.openqa.selenium.interactions.Actions;

Make sure to import the Actions class from Selenium; otherwise the code will not compile.
