enable_cache

enable_cache($enable=true,$refresh=true); - allow or prohibit the browser from using the cache. It is recommended to allow it for a slow Internet connection, and prohibit it if the Internet is fast, so that information from the Internet is loaded faster than from the cache.
To check whether cache is allowed or forbidden in the browser, you can use this function is_enable_cache.

The input function accepts parameters:

  • $enable – allow (true) or deny (false)
  • $refresh – should the page be updated (true) or not (false) after this command

    After testing, the function returns the result of its work to the script :
  • true – completed successfully
  • false – failed

    PHP example:

    <?php $xhe_host = "127.0.0.1:7013";
     
    //connect the object to control the emulator, if not already connected
    if(!isset($path))
       $path = "../../../Templates/xweb_human_emulator.php";
    require($path);
     
    //Start
    echo "<hr> <font color = blue> browser->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Enable cache:";
    echo $browser->enable_cache(true)."";
    echo $browser->is_enable_cache()." n";
     
    //2
    echo "2.Go to the page:";
    echo $browser->navigate("http://www.youtube.com")." n";
     
    //3
    echo "3.Disable cache:";
    echo $browser->enable_cache(false)."";
    echo $browser->is_enable_cache()." n";
     
    //4
    echo "4.Let's go to the page:";
    echo $browser->navigate("http://www.youtube.com")." n";
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7010"
    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> browser.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Allow cache:")
    echo(browser.enable_cache(true), "")
    echo(browser.is_enable_cache(), "
    ")
     
    # 2
    echo("2.Let's go to the page:")
    echo(browser.navigate("http://www.youtube.com"), "
    ")
     
    # 3
    echo("3.Disable cache:")
    echo(browser.enable_cache(false), "")
    echo(browser.is_enable_cache(), "

    # 4
    echo("4.Let's go to the page:")
    echo(browser.navigate("http://www.youtube.com"), "

    # end
    echo("<hr> <br>")
     
    # Quit
    app.quit()
