testing those links And now for the test drive... 146 Chapter 4 Here’s the new link. Notice, we only linked the words “Caffeine Buzz” so it looks a little different from the other link. And when you click on the link, your browser will make an HTTP request to buzz.headfirstlabs.com and then display the result. Here’s the page with the new link, just as we planned.
At Caffeine Buzz we use relative links to other pages on our site, and URLs to link offsite, like www.caffeineanonymous.com. there are no Dumb Questions Q: It seems like there are two ways to link to pages now: relative paths and URLs. A: Well, relative paths can only be used to link to pages within the same Web site, while URLs are typically used to link to other Web sites. Q: Wouldn’t it be easier if I just stuck with URLs for links to my own pages and outside pages? That would work wouldn’t it? A: Sure, it would work, but there’s a couple of reasons you don’t want to go there. One problem is that URLs are hard to manage when you have a lot of them in a Web page: they’re long, difficult to edit, and they make HTML more difficult to read (for you, the page author). Also, if you have a site with nothing but URLs that link to local pages and you move the site or change its name, you have to go change all those URLs to reflect the new location. If you use relative paths, as long as your pages stay in the same set of folders – because the links are all relative – you don’t have to make any changes to your element href attributes. So, use relative links to link to your own pages in the same site, and URLs to link to pages at other sites. Q: Haven’t we seen one other protocol? I kept seeing “file://” before we started using a Web server. A: Yes; good catch. The file protocol is used when the browser is reading files right off your computer. The file URL, getting connected for example, “file:///chapter4/starbuzz/ index.html”, tells the browser that the file “index.html” is located at the path “/chapter4/starbuzz/”. This path may look different depending on your operating system. One important thing to notice in case you try to type in a file URL is that the file URL has three slashes, not two, like HTTP. Remember it this way: if you take an HTTP URL and delete the Web site name you’ll have three slashes, too. Q: Are there other protocols? A: Yes, many browsers can support retrieval of pages with the FTP protocol, and there is a mail protocol that can send data via email. HTTP is the protocol you’ll be using most of the time. Q: I’ve seen URLs that look like this: http://www.mydomain.com:8000/ index.html. Why is there a “:8000” in there? A: The “:8000” is an optional “port” that you can put in an HTTP URL. Think of a port like this: the Web site name is like an address, and the port is like a mailbox number at an address (say, in an apartment complex). Normally everything on the Web is delivered to a default port (which is 80), but sometimes Web servers are configured to receive requests at a different port (like 8000). You’ll most likely see this on test servers. Regular Web servers almost always accept requests on port 80. If you don’t specify a port, it defaults to 80. you are here 147
