I am using api with oauth2, and need to refresh the access token when it expires. So I want to resent the request after the request is refreshed. I am concerning whether the NSURLConnection will change the http request object. Thanks in advance!

    Have you checked out the URL loading guide? It has this in a box in the text:

    When a client application initiates a connection or download using an instance of NSMutableURLRequest, a deep copy is made of the request. Changes made to the initiating request have no effect once a download has been initialized.

    So you can reuse your request as much as you like without fear of modification. NSURLConnection works with a copy of it.
