How to disable caching in WP Super Cache plugin for some objects like div with no-cache class? Or is it better to use another plugin? Or even without plugins?

More or less like this:

define( 'DYNAMIC_CACHE_TEST_TAG', '' ); // Change this to a secret placeholder tag
if ( DYNAMIC_CACHE_TEST_TAG != '' ) {
  function dynamic_cache_test_safety( $safety ) {
    return 1;
  }
  add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_cache_test_safety' );
  function dynamic_cache_test_filter( &$cachedata) {
    return str_replace( DYNAMIC_CACHE_TEST_TAG, "<!-- Hello world at " . date( 'H:i:s' ) . " -->", $cachedata );
  }
  add_cacheaction( 'wpsc_cachedata', 'dynamic_cache_test_filter' );
  function dynamic_cache_test_template_tag() {
    echo DYNAMIC_CACHE_TEST_TAG; // This is the template tag
  }
  function dynamic_cache_test_init() {
    add_action( 'wp_footer', 'dynamic_cache_test_template_tag' );
  }
  add_cacheaction( 'add_cacheaction', 'dynamic_cache_test_init' );
}

You set your DYNAMIC_CACHE_TEST_TAG, insert it at the right place in the template, respectively, the plugin will cache the page along with the value of the DYNAMIC_CACHE_TEST_TAG constant, and then use the wpsc_cachedata hook to replace it with the output of your function.

PS And there it seemed like it was necessary to play around with the checkboxes in the plugin settings, late initialization felts or something like that. It seems to be written about it on the plugin settings page.
