Memory buffer in a bash script

I have recently finished a script that will ask for a hostname and automatically take the argument of the function and ssh into one of my work servers.

Here is a copy of my script:

#!/bin/bash
echo "Provide hostname: "
read host

createSSHFunction()
{
    arg1=$1
    ssh $host
}
createSSHFunction $host

while((1)); do ~/sshScript.sh; done

What I notice though is say I want to ssh into one of the servers and I got disconnected, by instinct I will press the Up arrow key to redisplay the same argument I put in the last time. Here is an example of that:

    Provide hostname:
    crf-alpha
    support@localhost's password:
    Last login: Thu Jul 24 12:16:33 2014 from localhost
    [support@crf-alpha ~]$
Connection to localhost closed.
Provide hostname:
^[[A

Is there such a way to code in my current script where it will buffer anything I type last? So for example i ssh into the crf-alpha and I get disconnected. My script will run again prompting me to enter a hostname, I would like it so that if I press the Up arrow key, the last input I entered will re-display, so in this case crf-alpha rather than the weird symbol I always get.
