|
* Proxy which uses HTML5 session storage as its data storage/retrieval mechanism. If this proxy is used in a browser
|
* where session storage is not supported, the constructor will throw an error. A session storage proxy requires a
|
* unique ID which is used as a key in which all record data are stored in the session storage object.
|
*
|
* It's important to supply this unique ID as it cannot be reliably determined otherwise. If no id is provided but the
|
* attached store has a storeId, the storeId will be used. If neither option is presented the proxy will throw an error.
|
*
|
* Proxies are almost always used with a {@link Ext.data.Store store}:
|
*
|
* new Ext.data.Store({
|
* proxy: {
|
* type: 'sessionstorage',
|
* id : 'myProxyKey'
|
* }
|
* });
|
*
|
* Alternatively you can instantiate the Proxy directly:
|
*
|
* new Ext.data.proxy.SessionStorage({
|
* id : 'myOtherProxyKey'
|
* });
|
*
|
* Note that session storage is different to local storage (see {@link Ext.data.proxy.LocalStorage}) - if a browser
|
* session is ended (e.g. by closing the browser) then all data in a SessionStorageProxy are lost. Browser restarts
|
* don't affect the {@link Ext.data.proxy.LocalStorage} - the data are preserved.
