So far in this book, we've only really looked at single pages and responses to post-backs. As you know from browsing the web, one of the main features that it offers over traditional documents is the ability to link from one document to another using a hyperlink. Without hyperlinks, navigating around a website from one page to another would be very difficult. It would stop certain sites, such as search engines from being as useful as they are. For instance, browsing from a results page on a site such as Google to the results of a query would become a painful task – involving manually copying and pasting links at best.
In this chapter, we'll learn how to make use of hyperlinks that "glue" pages together in our own applications. We will:
Learn how hyperlinks are formed and used for joining static pages to each other
Examine how we can link to other types of files than just web pages, and how the requests for these linked files are dealt with
Look at how links can not only be used to take us from one page to another, but can also pass data around between pages
See how we can use hyperlinks for other functions, such as sending e-mails and running code within browsers
Learn how to reuse client-side resources that we've written by linking to external documents from within a web-page
