Plesk can redirect a domain or subdomain, but not a specific page.
If doing it through Plesk, you will create the domain (or subdomain). Then, under "hosting options", you will select forwarding or Frame forwarding. Enter the destination and now open up a browser and type the created domain; you will be redirected.
There may be times when you would like a specific page of your website to be redirected to another page. If you would like a specific URL to be redirected to another page, please use a website script or code. Here is a source of such codes:

Advanced Note: There is a third party module called isapi rewrite which you may purchase and have installed. This will allow you to use .htaccess redirects.
Advanced Note: If you are using server 2008 with IIS 7, there is a free module called URL Rewrite which has rewrite rules in the web.config file.
