Web Site "Lock-In"

Danborg writes "There's a great article over at ZDNet about annoying web sites that lock surfers inside a web site once they arrive. This practice, started by porno site operators, appears to have gone mainstream. Formerly respectable corporate sites like Home Depot now lock you in, disabling the use of the "Back" button. Fortunately, Top9.Com has generated a list of the offending sites. Is it a legitimate marketing technique? Or a highly annoying example of poor web site design?" I run into this dozens of times a day while reading story submissions. It never ceases to amaze me (but then again, old versions of Slashdot did the same thing, so who am I to judge?)

      In fact, Microsoft offers a freebie add-on called IE5 PowerTweaks. Among other things, the handful of tools includes menu items (on the Tools menu) called "Add to Restricted Zone" and "Add to Trusted Zone". This lets you manage your cookie-and-javascript-enabled sites without messing around in the "Security" dialog box for five minutes.

    I remember hearing some (MS I think) browser developer saying how they wanted to make a main-bar button that would toggle javascript, so you can stop a flood of popups fairly easily.

    It got dubbed the "porn button" and was, unfortunately, never included.

    Part of the problem is web-sites that use a 0-second refresh. For instance, go to this microsoft site and then try to hit the back button - it won't let you out! So Microsoft.com should also be on that list.

    The reason? People are too lazy to return a 302 Moved (like Google does for the I'm Feeling Lucky button) and instead use a meta refresh. Well, it's wrong!

    Browser writers (and Mozilla team): Could you let the back button disable the meta-refresh if you accidentaly back onto a meta-refresh page?

  5. Use window.location.replace('newlocal.html'); by cvd6262 · · Score: 5
    What urks me is that there are a lot of newer web designers who don't know how to correctly use javascript to forward the user to a new location. If they just say: window.location = 'newpage.html'; then when the user hits 'back' it will rerun the script and transfer them again.

    The correct way is: window.location.replace('newpage.html');. This replace the old page with the new in the browsers history.

    This practice, started by porno site operators
    Ballocks. The problem here isn't web sites trying to "lock you in" - it's crappy web designers showing poor engineering skills and lack of knowledge of their tools. Specifically, lots of these sites (homedepot is a prime example) use the nefarious META http-equiv="refresh" kludge instead of sending proper 302/303/etc redirection responses. They're using an HTML-level mechanism to perform an HTTP-level function. Nothing more, nothing less.

    If they wanted to lock you in, I would wager they could actually disable the Back button with JavaScript (I think some on-line banks do this so they can keep you from going "back" to a page providing info that you just invalidated by performing some transaction).

    I hate META http-equiv.

  8. A Mozilla solution? by ajs · · Score: 5

    Perhaps the right solution is to have Mozilla not fall for it. For example, one way that I know of that people do this is to have /index.html be a blank page with a META REFRESH or REDIRECT tag pointing to the real homepage. Why not have Mozilla detect the combination of "back" and META REFRESH or REDIRECT and simply not obey the tag?

    The other solution would be to take pages out of the history list when they contain a META REDIRECT REFRESH. That would also cause the back button to work as expected, perhap arguably more like expected.

    Do either of these solutions break any reasonable practices?

  9. Re:Lazy developers and dumb HTTP by artdodge · · Score: 4
    they have to work around the miserable way that HTTP handles state.
    Not the problem at all. You can handle state in at least two ways in HTTP (there are others, but some of them are patented :-P), neither of which necessitate the shoddy practices seen on theses sites.
    • Cookies (example: yahoo)
    • Use proper redirection (302 Found or similar) to a URL embedding a session ID (example: amazon) instead of the claptrap HTTP-equiv refresh crap these sites use.
    What kind of statefulness do you have in mind that Cookies don't deliver? (BTW: you might want to look at the most recent IETF drafts; Set-Cookie2 et al are much more mature than Netscape's hack.)

We would like to thank you for contacting us at homedepot.com and sincerely apologize for any inconvenience you may have experienced while using our Web site. Rest assured, we do not want to limit your access to the Internet from our site. Because the actual Web address for our home page is quite long and complicated (you can see it in the address field of your browser once you are on the page), we have simplified our Web address to www.homedepot.com to make it easier for our customers to remember and access. When you enter our address in your browser, we convert the simple Web address to the real Web page address. For that reason, the "back" button may not work in some browsers. Our technical experts are working to find a way to eliminate this process.

    1. Re:Home Depot's Offical Response by MrJay · · Score: 4

      Well, hitting the URL http://www.homedepot.com/ redirects you to the page index1.html. This page uses Javascript (uggh) to determine whether the user (ironically) has Javascript enabled in their browser:

      //Proceed only if the browser supports JavaScript.
      ..

      if ( browserSupp )
      window.location = "/" + siteName + "/HDUS/EN_US/pg_start.jsp";
      else
      window.location = "noscript.html";

      In pg_start.jsp, I can only speculate that a new session is created (the next URL has a session ID field) and various startup routines are executed.

      When you arrive at the homepage, the URL contains something similar to this:

      pg_diy.jsp?BV_SessionID=@@@@1850957283.0963009276@ @@@&BV_EngineID=cal ieli dldjbemfcfkmcficgkj.0">

      Given this information, I can make the following statements:

      • They are using Broadvision. Anyone who's used this horrible piece of proprietery crap knows how uncomfortable and cumbersome it is to work with.
      • They are heavy on the Javascript. IIRC, Broadvision sends various Javascript functions to accomplish mostly what can be done without Javascript. An expert web designer can build a complex site without a heavy and almost necessary reliance on Javascript.
      • HTTP and HTML should both be extinct. Perhaps this is why Home Depot opted for the expensive Broadvision. I bet they also paid through the nose for a BV tech to be on site. Yipee!!

      In all seriousness, this sort of thing can be avoided with a proper design. And the sheer difficulty of the whole process is nil.

    I went to the sites on the list that there was "no way" to get back to the previous site and I had almost no problem getting back in either Netscape or IE.

    Both browsers have an option in the back button to skip several pages back.

    - In Netscape, you just hold down the button for a few seconds.

      I don't really think that this law applies here. I'm no lawyer, but here is why: you can still access other sites through your book marks so you are not really 'locked in'. They do not control your browser completely so you can still exit by typing in a URL in the location bar. Since both Netscape and IE browsers support searching through the location bar you can always exit one of these site.

      While I do agree that this is bad practice on the site developers side, I do not think that it is against the law. Also how are you going to sue someone or take legal action if they are not in Arazona, or even the US? I imagine that since these sites have basically ben blacklisted on slashdot it is only a matter of time before most of them stop that practice anyway. I know that it is a cheezy way to keep visitors. Obviously if a site needs to do something like this then they have no content that will make people want to return.
