Drupal Authcache thrifty caching

If you successfully installed Authcache you might be think: "Why I need a separate caching for my authenticated user and customer? There is no difference on site."

You are right. Separate cache is used for different user roles. And if you want all your logged in users to use same cache and save some hardware resources then I can help you. Just create a small custom module and paste code below. It allow to generate same cache ID for different roles.

/** * Modify the properties used to calculate the authcache key. * * @see authcache_key_properties() * @see authcache_key() */ function YOUR_MODULE_NAME_authcache_key_properties_alter(&$properties) {  // create cache key for all logged in users (except uid=1)  if (isset($properties['roles'])) unset($properties['roles']); }

How to speed-up Drupal for logged in users?

How to speed-up Drupal for logged in users?

Drupal caching system works pretty fast for anonymous users. But when you logged in then site speed could be very creeping. It’s really bad for your customers, commentators, editors and you. It is really annoying to administer slowly back office. What should we do?

Here is a solution - Authcache module. Just try it. After main module installation some add-on modules maybe needed such as Authcache Form, Authcache Menu, Authcache User or Authcache Commerce. Also you will need to enable Authcache Builtin Storage Backend (or Varnish Storage) module to store your cached data. Next step is a simple configuration in 3-steps: 1. Enable needed user roles on module configuration page (admin/config/system/authcache). 2. Disable Drupal page caching for anonymous users and check that your expiration time is set (admin/config/development/performance). 3. Update settings.php file with needed backend configuration. You can use Memcache, MongoDB, Redis, Filecache or Varnish as a backends. Here is a good guide https://www.drupal.org/node/2160133 I really like Authcache configuration without using database ("authcache_builtin_cache_without_database" setting). Some pages speed for logged in users grows up to 3 ms.

Here is also a little advice how to save some hardware resources for caching if you have many roles and don't need role-specific caching. Do you use any other methods to speed-up Drupal for logged in users?

Select "Components" link of needed webform. Select "E-mails" tab. Edit or add e-mail configuration. On e-mail configuration page is important to select "Default template" setting and check "Send e-mail as HTML" if you want mimemail to work. Any questions are welcome.

Create new route: manifest.php + controller + views - part 2

If you want some new service or unique page - creating new controller is a good choice.

Add to settings/manifest.php "routes" part new info about your route:

'routes' => array(  'user_auth_social_vk' => array( // Unique name of route. Better name it modulename_function_name   'route' => 'user/auth/social/vk', // Your route path   'defaults' => array(    'module' => 'custom', // Module name    'controller' => 'auth', // Controller name    'action' => 'vk', // Action name   ),  ), ),

Copy controller that you want to modify to your controllers directory or create new one. Templates are placed in module views/scripts/{controller name} directory. Copy templates you need (one per action). For example: controller file name is UserController.php with actions homeAction() and indexAction(). You need to create 2 temlates views/scripts/user/home.tpl and index.tpl in the same dir.

Create widgets: content.php + widget - part 1

If want to redefine some part of the page this is a good way. Check out that the part you want to be redefined is a widget: find parent <div> with classes such as "generic_layout_container layout_core_content" - this is a widget. Second class may help you to locate a widget. In this example widget name is "content", located in "Core" module directory. Add to settings/content.php in your module dir some information about widget, like this:

// My new widget array(   'title' => 'My new widget', // Widget title for layout editor in admin panel   'description' => 'Displays my new widget', // Widget description for layout editor   'category' => 'Custom', // Category (or just a module name) for layout editor   'type' => 'widget', // Widget type   'name' => 'custom.mywidget', // Widget name for code. Better format will be as modulename.widgetname in lowercase.   'defaultParams' => array( // Widget parameters     'title' => '',   ) ),

You can find widget info in original module content.php. Now you can copy and modify the widget.
