HTTP Conditional GET support

> Hi
>
> Is anyone aware if HTTP conditional GET support is implemented in Orbeon
> forms?
> I found this past thread from 2007 discussing just this, but can find
> nothing newer so maybe this was never implemented.

>
> If it is not supported, I will explore the <header/> element to see if I can
> add a "if-modified-since" header to the HTTP request.
>
> In terms of the HTTP response, is it possible to retrieve the status code?
> i.e. I would like some actions carried out if a 304 was returned and other
> actions to be carried out if a 200 is returned. The xForms events
> "xforms-submit-error" and "xforms-submit-done" don't appear to the level of
> detail required for this, or is a 304 response going to notify
> "xforms-submit-done" and the cached XML is put into the instance specified
> by submission element?
>
> Any thoughts would be appreciated. Thanks in advance.
