Autossh might do this better/more elegantly, but a quick and dirty solution
would be something like this:
1) Set up certificates so that "ssh server" from your machine will
automatically log in to the server without prompting for a password.
2) Write a script to see if ssh is running and run it if it's not, e.g.
#!/bin/sh
netstat -na | grep LISTEN | grep 80 || \
/usr/bin/ssh -fnN -L 80:en.wikipedia.org:80 server
3) Add an entry to your crontab to run the script every X minutes.
