If you want to send an arbitrary amount of data to your server, POST is the only reliable method to do that. GET would also be possible but clients and servers allow just a limited URL length (something like 2048 characters).

As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with
```
<html> 
  <head>
    <title>runthis</title>
    <script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
    <script type="text/javascript">
        $(document).ready( function() {
            var x = $("#foo").html();
            alert( typeof(x) );
        });
    </script>
    </head>
    <body>
        <div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
    </body>
</html>
```
The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.

edit: Don't pass a string as the parameter data to .post() but an object, like
```
var data = {
  id: currid,
  html: div_html
};
$.post("http://...", data, ...);
```
jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().
```
var data = 'id='+ escape(currid) +'&html='+ escape(div_html);
```

I don't see why you shouldn't be able to send html content via a post.

if you encounter any issues, you could perhaps use some kind of encoding / decoding - but I don't see that you will.
