Multiple interpreter declarations

Hi,
I am writing a shell script that connects to a remote server and performs some tasks on the server and exits.
Since i am using a ssh connection, i am using a "expect" utility to supply the password automatically (which is present within the script).

In order to use this utility, i need to declare the executable path at the beginning of the script using interpreter declaration.
something like this: #!/usr/bin/expect

This works fine so far.
However, i am using this script as part of CGI-programming too.
The input/output of this script is available via web browser with the help of cgi-programming.

But, the real problem is , in order to achieve cgi-programming with this script, i need to have a interpreter declaration about the path of the shell.
something lik this: #!/bin/bash

Now,, the problem is , i cant have both interpreter declarations in the script.
It throws error if i try.
So, it leaves me with an option to use any one of the interpreter declarations.

is there any way or a workaround to get both the features.
What i mean is - is there any way to declare both the interpreters ( #!/usr/bin/expect and #!/bin/bash) within my shell script.

Appreciate your help.
Thanks.

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
