Hi,

I've gone through the tutorial, and would like the comments to be  
submitted via ajax (as well as standard non-javascript submission).  
I'm reasonably happy with what to do in the browser (via MooTools as  
it happens), but server side I'm not sure:

- Ideally, I would like the Ajax submission use the same url as the  
standard submission

- So would I need to "route" based on the X-Requested-With header, to  
a new action: say 'PostCommentsAjax' action? How would I do this?

- Should this PostCommentsAjax action be a subclass of  
PostCommentsAction? I would like to avoid copy/pasting the code from  
PostCommentsAction.

For output I would prefer to

     - Have all validation happen server-side, so I don't need to  
repeat logic in the browser.

     - Return HTML as output. This is so the Javascript doesn't need  
to know about the structure of the comments, it can just inject the  
html into the appropriate place on the page. However, it might be a  
good idea to actually return a JSON object, with the html as one of  
the values, as I might want other parameters passed back, like  
"success:true" or something.

Can I ask for some pointers on how to achieve this?

Thanks,

Michal.
