Vodafone Move Invites Web Development Chaos 192

hoagiecat writes "Web developers want mobile phone users to be able to access their sites, but mobile browsers generally choke on heavyweight HTML put together for traditional Web browsers. A host of services have sprung up that allow two sites — one for mobile users, one for PC users — to coexist at the same URL, with the browser's user agent string distinguishing between the two. Vodafone has come at the problem from the other end, offering a new service that translates traditional Web pages into mobile-friendly ones on the fly — but it strips out the user agent in the process, breaking sites designed around the other strategy. And Web developers are mad. Will similar moves by other carriers disrupt this nascent Web development ecosystem?"

    Because I'd love to do without the feature (read: crap) heavy pages and go straight to the content.

      Straight to the content would be nice, but be careful what you wish for... There's no way advertisers are going to accept the idea that mobile versions of pages have no ads. With the screen area so small what will happen is that ads will appear on separate screens before the content you're trying to view.

      Desktop browser ads are mild by comparison. They sit at the top or the side, easily ignored. The worst they ever manage is to waste a bit of bandwidth. I predict people with more powerful phones will soon be spoofing non-phone user agents in an effort to dodge the evil phone versions of ad-supported pages.

      Why dont people just use media="screen|handheld|print" along with optimised code to a) reduce the amount of code sent in the first place, and b) position it properly based on the client I realise you have to download the same amount of HTML which might not be optimised for slower connections but seriously ... isnt that the entire purpose of the media="" attribute ??

        Which is the entire point. Imagine the use case of reading an article on Wikipedia, let's say a long one such as Tetris [wikipedia.org] or George W. Bush [wikipedia.org]. On a PC with a full-page screen, full CPU, full RAM, and a transfer cap in the tens of gigabytes per month, you want to load the article's full text. On a handheld device with a smaller screen, smaller CPU, smaller RAM, and a smaller transfer cap, you may want to load just the lead section and the table of contents, then load other sections only once you follow a link f

            An Internet media type [wikipedia.org] is the same thing as what used to be called a "MIME type". HTML with one page per section and HTML with the whole article on one page are both of type text/html;charset=utf-8, regardless of the size. How would you propose extending HTTP to add Accept-Length:?

            Of course clients and servers need to understand such a parameter

            Good luck. A lot of shared hosting companies give so little of a damn about conforming to web standards that they insert invalid HTML into every page that they serve and won't add new Internet media types except to customers on

Most developers are to lazy to use such tools and those that aren't are mostly purists that don't think making multiple versions of content for different uses is acceptable.

    As a Vodafone "business" customer for the last 15 months, Vodafone is doing exactly what the article claims:

    Companies that are on Vodafone's "white list," which is a group of Vodafone-approved services, were notified of the change and the operator is passing the user agent correctly for those services, developers say. ... It's unclear if Vodafone removed the user agent capability for "diabolical" reasons, such as to maintain firm control over the content that users can access, or if it was a legitimate mistake, Harper said.

    The issue at Vodafone is they need a revenue engine that cannot be hampered so they artificially create one. With the recent court rulings over VoIP services like Truphone, Vodafone is seeing disruptive technologies come into play. This is just business doing the right thing for itself but not for the customer.

    For what it is worth, within the group of people I work with (about 2000 people), many of us are using Truphone over the wireless broadband we are provided. Suddenly, my 400-600 pound mobile bills are now down to 50/month with loads of unused minutes rolling over. The story is similar with many other people here and across other networks. Are you surprised?

To make the problem even worse, it then refuses to pass across files that the phone would be perfectly capable of accepting.

      Vodaphone have two gateways - the internet gateway, which is unfiltered, and the WAP gateway, which rerenders the page to fit well on a mobile phone. Both have their place, and I prefer different ones for different sites.

      Many sites simply will not render well on a phone, no matter how html compliant their browsers are (and most modern phones have full featured browsers these days). The vodophone gateway makes these usable (and for older phones with only WAP browsers it makes browsing actually possible).

    Hmm... I wonder how this fits in with Vodafone's charging.

    By breaking the functionality that allows operators to display the mobile optimised pages, they are forcing people to download more content. Even if they only charge for the amount transmitted to the mobile after they've processed it, that's still likely to be significantly more data than people would have had with the optimised pages. And if they charge for the size of the original page (and I wouldn't put it past them), they really are ripping people off.

    Either way, I would not be happy with this change if I was on a limited data tarrif.

    A host of services have sprung up that allow two sites -- one for mobile users, one for PC users -- to coexist at the same URL, with the browser's user agent string distinguishing between the two.

    Don't I know it. I use a BlackBerry to surf the web most mornings on the train, and I see these all the time. I've learned to avoid some links specifically because I don't want to waste my time trying to navigate a crappy mobile version of a site. For example, I no longer click on any Reuters or USA Today news links on Slashdot or Digg, because rather serve me the article I asked for, these sites entirely ignore the URL I sent it and drop me on their mobile page, from which (I guess) I'm expected to navigate to the thing I originally wanted. Unfortunately the mobile page contains links to news categories and a list of the most popular stories, and it's usually impossible to find the one I wanted. Many news sites use similar services. The big provider seems to be Crisp Wireless [crispwireless.com], which proudly announces its responsibility for this crapiness at the bottom of each mobile page.

    My newest pet peeve is the BBC News site. If I type "news.bbc.co.uk" in my desktop browser I get the BBC News page. But on my BlackBerry the site ignores the URL and "helpfully" redirects me to a page where I can select whether I want their Mobile or Desktop edition. It's nice that I at least get an option, but it adds a page load to the process of simply reading the news. And when I select the Desktop link they send me to the main BBC site, not the News site, so I get to make a third page load when I click on the News link to visit the page I originally requested about a minute ago.

    How are these mobile sites supposed to help us again?

      It amazes me that I still see signs of this thinking. Web pages and services are tailored to small screens and people expect that to create the mobile internet. It won't. There is only one internet, and if your device cannot access it, you're out of luck. There is only one internet.

    The site content shouldn't need to change - only the presentation.

    All that needs to be done is to serve up a different style sheet depending on the user agent, or a default 'safe' stylesheet, or none at all.

    Determining which style sheet to use will necessitate peeking at the user-agent so Vodaphones approach could be problematical. Maybe if they had a meta tag to tell their gizmo not to process the site.

      As someone who's been through that: it doesn't work.

      You see, the mobile stylesheet has suspiciously many entries of "display:none" if you go this way. Which means you discard many of the non-essential elements for the mobile version and reorder the rest to fit a mobile screen, but the mobile users still download the entire damn thing.

      And downloading things you don't even SEE is far from perfect for the expensive/slow access points on a mobile device.

      Certainly nice that CSS has the feature, but it's not the ultimate solution.

        A lot of that really depends on the kind of content you're talking about. For example, on a page with numerous large images one might consider inserting place-holder elements onto which a background image is set via css. By taking this approach you're able to avoid inserting the images directly and instead give css considerably more power in presenting your page to different media types.

Then instead of trying to guess the media type from the user agent string, the server will know for sure. For example a request might have the HTTP header "MediaType: display/mobile;geometry=288x384" and a 2nd header "MediaType: audio/stereo;format=mp3,ogg,flac". The
