Running a script on multiple machines

To clear the web cache on my web server, I run this command:

find $APACHE_HOME/cache/plsql/plsql -type d -name "[0-9]*" -exec rm -R {} \;

To clear the cache on all the web servers(we have 4), I log on to any one machine, clear its cache, ssh to another machine, clear cache etc;

Is there any way to write a script so that this operation can be performed in one script ?

In other words, the script automatically ssh's into the 2nd server, clears the cache and then logs on to 3rd server and so on.

The ssh is over a trusted network and I am using the same account on each of these boxes so I am not prompted for password when going from one machine to another.

I tried to write such a script but what happens is although it logs into the other machine, I see a prompt for the other machine and when I exit it, I am back to the original machine. The script then runs on the original machine.

The shell is ksh and the OS is Solaris 2.8.

Thanx
