Work with multiple pages on the iPad


Manipulate multiple pages with the iPad

Like any self-respecting browser, Safari will keep multiple pages open at once, making it easy for you to switch among them. You can think of it as an alternate version of tabbed browsing, the feature you find on desktop Safari, Internet Explorer, and Firefox, which keeps a bunch of web pages open simultaneously - in a single, neat window.

The beauty of this arrangement is that you can start reading one web page while the others load into their own tabs in the background. On the iPad, it really works like this:

To open a new window, tap the the button on the top-left side of the menu bar. The current web page shrinks right into a mini version. Tap New Page to spread out a new, untitled browser page; now you can enter a previous address.

To switch back to the first window, tap the button again. The thing is a grid of up to nine open pages, looking kind of like baseball-card versions of the larger selves. Find the page you want to see again and tap it to open it full-screen. You can open another window, and a fourth, and so forth, and jump among them, using these two techniques.

To shut a window, tap the button. In the collection of shrunken pages, locate the miniature window you want to close, and then tap the button at its top-left corner.

iPad pop-up blockers, cookies, and security

Internet criminals will try to rip you off regardless of what browser you use. Phishing - when a devious website masquerades as a legitimate site to dupe people into entering personal information - has long been a problem. 'Pad- Safari has a Fraud Warning setting, which alerts you when you might be on a fishy, phishy site. You can switch it on in Settings, then Safari.

And also the world's smarmiest advertisers have been inundating us with pop-up and pop-under ads for a long time - nasty little windows that appear in front of a browser window or, worse, behind it, waiting to bug you whenever you close the front window. They're often deceptive, masquerading as alert or dialog boxes, and they'll do absolutely anything to get you to click them.

Fortunately for you, Safari comes set to block those pop-ups so you aren't seeing them. It's a war available - but a minimum of you have some ammunition. The thing is, though, pop-ups are sometimes legitimate - notices of new banking features, seating charts on ticket-sales sites, and so forth. Safari can't tell these pop-ups from ads - and so it stifles those pages, too.

How to proceed? If a site you trust says "Please turn off pop-up blockers and reload this site," you know you may be missing out on a useful pop-up message. In those situations, you can switch off Safari's universal pop-up blocker. From the Home screen, tap SettingsÆSafari. Where it says "Block Pop-ups," tap the On/Off switch.

Cookies

Cookies are something similar to web page preference files. Certain websites - particularly commercial ones like Amazon.com - deposit them on your hard drive like little bookmarks, so the site remembers the next time you visit. Ever notice how Amazon.com greets you with "Welcome, Leroy"? It's reading its cookie, left behind on your hard drive.

Most cookies are perfectly innocuous - and, in fact, are extremely helpful, because they help websites remember your tastes. Cookies also spare the effort of having to type in your name, address, and so forth, every time you visit these sites. But fear is widespread, and also the media fans the flames with tales of sinister cookies that track your movement on the Web. If you are worried about invasions of privacy, Safari is able to protect you.

To check all of this cookie security out, in the Home screen, tap Settings, then Safari. The options here are like a paranoia gauge. If you click Never, you create a polymer shield around your iPad. No cookies can come in, and no cookie information can go out. You'll probably discover the Web a very inconvenient place; you'll have to re-enter your information upon every visit to the site, and some websites might not work properly at all. The Always option means, "Oh, what the heck - just gimme all of them."

A good compromise is From Visited, which accepts cookies from sites you need to visit, but blocks cookies deposited on your iPad by sites you aren't actually visiting - cookies you get, say, from an especially evil banner ad that a hacker has planted on a page. There are a number of of those these days. The Safari settings screen also offers a Clear Cookies button, as well as Clear History and Clear Cache buttons.

A cache is a little patch of the iPad's storage space where your iPad retains equipment of web pages you visit - the page's graphics, for example. The idea is that the next time you visit the same page, the iPad won't have to download those bits again. It's already got them aboard, so the page appears much faster. If you worry that your cache eats up space, poses a burglar risk, or is confounding a webpage, tap this button to erase it and start over.
