header-name The name of the previous header. If header-name is null, this function returns the name of the first HTTP header.
This function iterates over the HTTP headers included within a request. Calling it with NULL causes it to return the name of the first header. Subsequent headers are retrieved by passing the function the name of the previous header. This function returns NULL when called with the name of the last header.
Calling this function repeatedly returns all the header fields exactly once, but not necessarily in the order in which they appear in the HTTP request.
