send headers after redirect: HTTP_X_REQUESTED_WITH

[jjshell]

Hi,

I have built an application which reacts differently given the request context, if a page is requested asynchronously, for example.


The problem is, when you submit a form asynchronously and redirect, the result cannot be detected with HTTP_X_REQUESTED_WITH. And my application needs to know if a redirect comes from after an asynchronous submission or not.

I came to the conclusion that easiest way to proceed is to mimic a xmlhttprequest request in the redirect. It avoids the use of sessions.

Is it a good idea?

If yes, how would you add headers that do what I want?

header('Location: '.$url);
die();

You could pass a query string argument.

I think I will go for sessions after all... It seems quite logical. I'm not sure this kind of data belongs in the query string (SEO-wise, or just for user friendliness).
