Hi, I found this sample http://developers.arcgis.com/en/javascript/jssamples/exp_webstorage.html, but I found some problems to download and execute it. The problem is that when the XMLHttpRequest request pass throw my PHP proxy, the encoder generates a corrupted base64 tiles. And no more corrupted tiles when I display a Map service that not require a proxy. there is my PHP proxy code :
<?php
/***************************************************************************
* USAGE
* [1] http://<this-proxy-url>?<arcgis-service-url>
* [2] http://<this-proxy-url>?<arcgis-service-url> (with POST body)
* [3] http://<this-proxy-url>?<arcgis-service-url>?token=ABCDEFGH
*
* note: [3] is used when fetching tiles from a secured service and the
* JavaScript app sends the token instead of being set in this proxy
*
* REQUIREMENTS
* - cURL extension for PHP must be installed and loaded. To load it,
* add the following lines to your php.ini file:
* extension_dir = "<your-php-install-location>/ext"
* extension = php_curl.dll
*
* - Turn OFF magic quotes for incoming GET/POST data: add/modify the
* following line to your php.ini file:
* magic_quotes_gpc = Off
*

*
* 'url' = location of the ArcGIS Server, either specific URL or stem

You make the feature in your ArcGIS and then you share it to your ArcGIS Online account. By default it should go to your My Content tab. When sharing it you should adjust the setting so users can edit. Then you have to make a Map with it and share it. Hi Robert, Could you tell me, if we can insert this layer in a web application without creating a map with it on ArcGIS Online? I try to add only the layer without creating a map with it in ArcGIS Online to my web site using the APIs ArcGIS REST and JavaScript. Is it possible?
