    The whitespace.gov site has lots of whitespace characters.

    Hmm... Freudian slip? FWIW, most of the whitespace is probably generated by the ASP technology they used. Spots where code goes can often generate unexpected whitespace. It's just a side effect of using scriptlet-type technologies.

    Don't get me started on the "correct" way to write ASP. The tag-substitution gobbldy-gook encourages all kinds of bad page-development practices. The request-time attributes + templating taglibs seen in JSP provide a much cleaner separation between logic and HTML.

    The whitehouse.gov site uses more GIFs than PNGs.

    Ouch. Welcome back to 1996. Web developers looking for the smallest file size really need to learn that there is such a thing as palletized PNGs. They're even smaller than GIFs, even.

    The whitehouse.gov site uses heavy JPG compression.

    This is one place where my reaction is "BFD". As long as it looks acceptable under most circumstances, the people with the carefully color calibrated monitors (*cough*yeslikeme*cough*) can suffer a bit. Heck, half the JPGs on the internet look like garbage, so I'm not too worried about artifacting in the gradients.

    The whitehouse.gov site uses IIS 6.0. The whitehouse.gov site uses ASP.NET 2.0.

    Can we choose the right technologies for a website? No we can't! Thankfully, the President isn't hired to choose the best technology to run his website. ;-)

        Like most PHP sites, the aspx extension is a dead giveaway :-) ASP.NET MVC is url based, just like a good mod_perl app or a rails app.

        Many, many ASP.NET sites use URL rewriting. http://www.yafla.com/dforbes/The_Best_And_Worst_of_2008/ [yafla.com] goes to an aspx page. http://www.yafla.com/dforbes/Could_Microsoft_be_the_Patron_Saint_of_Firefox/ [yafla.com] goes to the same aspx page, albeit with different parameters.

      Whilst I'm a fan of PHP myself, I have to say the new ASP.NET MVC framework is rather good.

      It really does beat hands down anything in the PHP world in terms of how quickly you can get something up whilst maintaining quality. I'd argue partly this is because of the Visual Studio integration and the power of Visual Studio to start with.

      I wouldn't ever build a live app. in web forms, but I could be pretty tempted with the new MVC framework I have to admit. The various PHP frameworks out there that perform a similar task such as CakePHP could learn a lot from it in terms of how quickly you can build with it without the usual sacrifice of quality of software you get with Microsoft's tools (again, web forms for example).

      Of course, the thing is as well, the Microsoft platform is slowly getting better, Windows Server 2008 and IIS 7 really aren't that bad, performance isn't too much different to Apache/PHP now and security since .NET is much improved. Of course, Apache was always pretty good so to say IIS is improving doesn't mean much in that context but certainly combined with .NET MVC I think the whole LAMP platform needs to watch out. The various PHP frameworks like Cake could do things such as dropping the stupid cake bake crap that fails half the time on Windows and is pretty much undocumented (It has one page in the docs that don't explain much beyond what it's for). In contrast Symfony is absolutely fantastic on documentation and so is Zend, but it's still much more hassle, and there's still many more security pitfalls you have to keep an eye on vs. ASP.NET MVC.

      I'd probably like Java, but I've never used it professionally, only academically so can't compare with that. At the end of the day though, my point is that with ASP.NET MVC I can build a high quality site much more quickly and with much greater confidence than I can with any PHP framework right now.

    <a id="ctl09_rptNavigation_ctl00_rptNavigationItems_ctl01_hlSubNav"...

    Sorry bud, they can't really be removed on the server side - these are controls embedded in controls embedded in controls. Maybe a slight shaving of rptNavigationItems down to rptNavItms or something, but the long name is to be able to reference the embedded controls.

    Please try again...

      Sure you can. Create your own hyperlink control inheriting from the one in ASP.NET and exclude writing the id.

  • They could fix these perf problems instantly using the RPO (www.getrpo.com). If anyone knows the developers, let them know

      Its a great looking site, and since we're setting a new path for the country i agree lets fix it now and move forward.

    Most of the optimization suggestions in TFA are going to offer no real performance benefit. With gzip on, whitespace, long ID's & viewstate make pretty much no impact on the final page weight, but doing these "optimizations" is going to make your page a hell of a lot harder to maintain. Don't believe me, go to webpagetest.org [webpagetest.org] and have a look, HTML accounts for only around 5% of the final page size. The best thing these guys could do to optimize the site would be to
    • combine the css and javascript files.
    • minify the javascript (as it is its taking up around 20% of the page weight)
    • perform more aggressive css spriting of the gif and jpeg images to slash the request count further.
    • remove ETag headers and add far future expiry headers to the images to speed up repeat page views and cut down on 304 responses from the server.

    Who cares about a 30 byte http header when your page is over 800k and ~45 requests, there's plenty of low hanging fruit to pick first. Interesting thing is in the post above a tool called the rpo is mentioned, it seems to do most of the important optimizations automatically.

    Reducing their bandwidth and server load is just not a big deal. (See Akamai [wikipedia.org] and note that the whole site takes the path that the "image" request takes in that diagram.)

  • This is a classic one:

    ASP.Net has built in defences against XSS which are enabled by default. Most sites will however only catch this on the last line of defence; the server-side request causing HTTP error unless manually handled or overridden. It looks like this site also doesn't do any input validation for tags either causing said errors.

    Really, you need to switch off the XSS checking and instead HttpEncode all the inputs manually so at least you don't break the site for potentially dangerous requests.
