Thanks for your reply.

By "variable name" I mean the name of the field that contains the data I have to send in post.

Like a html form for example:

Code:

<form method="POST" action="http://my-server.address/page.php">
   <input type="text" name="phone" value="1234"/>
   <input type="text" name="address" value="my street"/>
</form>

So I have to find the field name containing the json stiring to send to xbmc, like:

Code:

<form method="POST" action="http://xbmx.ip.address/jsonrpc">
   <input type="text" name="jsonrpc???" value='{"jsonrpc": "2.0", "method": "JSONRPC.Introspect", "id": "1"}'/>
</form>

I hope is more clear now.

Thanks.
Bye.
