Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e.g., in search results, to enrich docs, and more. This preview shows page 6 - 8 out of 13 pages.

In addition, in Chrome, these sites aremarked with “Not Secure” in the topbar of the browser.HTTPS works in tandem with anotherprotocol, SSL (for Secure SocketLayer), which needs to be enabledon the server for secure transactionsto work. Hosting companies haveoptions for enabling SSL, often for free.Keep in mind that HTTPS protectsform data as it is sent to the server,but doesn’t do anything to make yoursite “secure” and safe from hackers.PERFORMANCE TIPIf you want to minimize round-tripsto the server, include slashes at theend of directory names in URLs inyour links.Part I.

THE ANATOMY OF A WEB PAGEWe’re all familiar with what web pages look like in the browser window, butwhat’s happening “under the hood”?At the top ofFIGURE 2-3, you see a minimal web page as it appears in agraphical browser. Although you see it as one coherent page, it is actuallyassembled from four separate files: an HTML document (index.html), a stylesheet (kitchen.css), and two graphics (foods.pngandspoon.png). The HTMLdocument is running the show.HTML DocumentsYou may be as surprised as I was to learn that the graphically rich and inter-active pages we see on the web are generated by simple, text-only documents.The text file behind the scenes is referred to as thesource document.Take a look atindex.html, the source document for the Jen’s Kitchen webpage. You can see that it contains the text content of the page plus specialtags(indicated with angle brackets,<and>) that describe each element onthe page.Providing the URL for a directory (ratherthan a specific filename) prompts the server tolook for a default file, typically calledindex.html.index.htmlSome servers are configured to return a listing of thecontentsof that directory if the default file is not found.FIGURE 2-2.Some servers display the contents of the directory if an index file is notfound.
