You could create a simple ftp-script. It should remove the current content of server 2 and copies all the new content from server 1 to server 2.

You can choose to call this program from inside your cgi-app or through a schedular, depending on when you want your update to be done.

Update

There is another quick solution along the lines of: 

[user@server1]$ tar -czvf - web/ | ssh user@server2 'rm -rf web/ ; tar
+ -xzvf -'

From man ssh to login without a password:: 

ssh implements the RSA authentication protocol automatically. The user
creates his/her RSA key pair by running ssh-keygen(1). This stores the
private key in $HOME/.ssh/identity and the public key in
$HOME/.ssh/identity.pub in the user's home directory. The user should
then copy the identity.pub to $HOME/.ssh/authorized_keys in his/her ho
+me
directory on the remote machine (the authorized_keys file corresponds 
+to
the conventional $HOME/.rhosts file, and has one key per line, though 
+the
lines can be very long). After this, the user can log in without givin
+g
the password. RSA authentication is much more secure than rhosts authe
+n­
tication.
