Use this javascript to set a referrer, meaning that if a user visits a page directly it gets referred to the main page. This way you enforce users to always use the mainpage:

<code javascript>
<script type="text/javascript">
if (document.referrer !== "http://mainpage.url.com/") {
    window.location.href = "http://mainpage.url.com/";
}
</script>
