Some informational sites want users to access pages in a certain order. They want to prohibit users from jumping directly to a bookmarked page later in the sequence because the data on the pages may have changed since the user bookmarked the page. Create two pages. The first page should be a normal HTML page with a link to the second page (which should be a servlet). If a user accesses the first page and then follows the link to the second page, it works normally. But, if the user directly types in the address of the second page (or follows a link from a page with a different name than the first page), they should get sent back to the first page automatically. Hints:

Use response.sendRedirect to send users back to page1. See the description of send-Redirect on the bottom of the previous set of exercises.

It is not necessary to make page1 be a servlet, but page2 must be.
