401 Unauthorized at Replay time

Hi ,

I'm trying to replay a script but its throwing me an replay error ::HTTP status code=401 (Unauthorized).Correlated the dynamic value (ouaf Security Token).

tried using below options

-Using a valid Web_set_user function.

-Tried changing options to "winInet" Instead of sockets.

above options didnot work.

Can any one Help me on this

Thanks in advance
