and then do a response.SendRedirect(URL) to some other URL, will i be able to read this header value at that app?
No. The response headers are read by the client and then discarded. (Besides, they're response headers, and thus not part of a request.) You'll need to put any data you want to reach the final destination as URL parameters.

There's no redirection here, so the example is not relevant.
