Insert data into HTML5 Web Storage from the server

Question

Can I insert data into Web Storage from the server, like I do it with cookies by setting a header. By Web Storage I mean HTML5 localeStorage and sessionStorage.

Answer 1

Of course. But your server need to inject the code into the page it is serving.

From server this code need to be injected somewhere to the body or an extra javascript file.

<script type="text/javascript">
    localStorage[key] = myValue;
</script>

Answer 2

Using C# as an example;

ClientScript.RegisterClientScriptBlock(GetType(), "sas", "<script>  
if(typeof(Storage)!=="undefined")
{
// Yes! localStorage and sessionStorage support!
// Some code.....
}
else
{
// Sorry! No web storage support..
};</script>", true);
