Can lftp run a script without exiting at the end?

[George Entenman]

I would like to write a script for lftp that would do things that 
I usually do for a particular site (log in, cd and lcd to the usual 
directories, etc.).  I'd then like to start lftp with the -f <script> option, 
have it execute those commands and then leave me in the state that the script 
ended in (e.g., logged in, in specific directories, etc.).

Any suggestions would be appreciated.
