+Caching of different request methods
+````````````````````````````````````
 
+Most of the time you should not change the ``methods`` option. However if you are working for example with HTTPlug
+based SOAP client you might want to additionally enable caching of ``POST`` requests::
+
+    $options = [
+        'methods' => ['GET', 'HEAD', 'POST'],
+    ];
+
+The ``methods`` setting overrides the defaults. If you want to keep caching ``GET`` and ``HEAD`` requests, you need
+to include them. You can specify any uppercase request method which conforms to :rfc:`7230`.
+
+.. note::
+
+    If your system has both normal and SOAP clients you need to use two different ``PluginClient`` instances. SOAP
+    client should use ``PluginClient`` with POST caching enabled and normal client with POST caching disabled.
