If you give someone a link to complete a new form in SharePoint (like a survey), they normally get returned to the default list view after they submit the response. However, you can redirect them to some other page by adding the ?source parameter to the end of the URL link.

http://<site>/sites/sandrateamsite/Lists/Poll/NewForm.aspx?source=http://<sites>/sites/sandrateamsite/Lists/Poll/summary.aspx
What they see after submission without the ?source parameter:

If you have ever been taken to a “thank you” page after submitting a form online, this is the technique that they are using.
