Coding for the New Year

Just a quickie before diving into 2011;

And this is how I feel about 2011:

  1. Thanks for the DoNotTrack plugin! I’m testing it on my second blog now, and it seems to work fine blocking Quantserve so far.
    However, it breaks some existing, “good” document.write by making every written text lower-case. My quick solution was to replace the beginning of function sanitizer in the JS file with tSL=tS.toLowerCase(); if((tSL.indexOf(unescape('%3Cscript'))!=-1)&&(tSL.indexOf(unescape('src='))!=-1)) {for(x in spy){if(tSL.indexOf(spy[x])!=-1){ (and leave the rest unchanged), i.e. use the toLowerCase result (in tSL) only for comparison, but not for modification and output.
    Also, do you think it’s okay to include this short Javascript inline in the header, instead of in a separate file? This would remove this additional HTTP request to load the .js file.

      • To be nitpicking, you got one difference: you’re assigning the lower-cased modified version to the output with tS=ttS.replace(...) – but that doesn’t really matter since it only affects additional text that’s written together with an offending tracking script in the same document.write command, and everything will be fine for “good” document.writes. 🙂
        Putting it inline: well, the fewer external files the browser has to load, the faster the page will be loaded – though there won’t be much difference here with this small file, I guess, and it’s still faster than the Quantcast file(s).

        • it’s correct that loading less external (js- and css-) files is recommandable, and in general there are a lot of js/css-files that are included by plugins (including mine, I admit). That’s why I use the CSS/JS booster plugin (made in Germany) to move all CSS and all JS into one file each. Great plugin, really!

  2. Ok I want to include the tracking but only remove the call for the pixel, is this possible? to get rid of this error
    Resource interpreted as Image but transferred with MIME type text/plain.”

  3. Hi Frank, thanks for this awesome script.
    Today I visited my site without being logged in and noticed that something was loading from again and it was really slow (As in won’t load at all).
    It looks like the Stats script got updated and no longer uses document.write to insert the Quantcast script. It uses an asynchronous method now. Therefore, the notrack script doesn’t seem to work properly anymore.
    It still uses document.write to insert the Stats smiley though…

  4. Hlw sir it works like a charm. But i have an issue with it. After installed ur plugin my site page loading speed got down a bit.
    Before install:-
    According to gtmetrix com my site
    Page Speed Grade: (A) 99%
    YSlow Grade: (A) 92%
    After install:-
    Page Speed Grade: (A) 95%
    YSlow Grade: (A) 93%
    My page loading speed got down 4% while YSlow Grade got up 1%. Which made me upset. Is there any solution for me?
    So what do you think about it. Waiting for ur response.

    • I you check out, you can see the main differences between your site without (first) and with (second) WP DoNotTrack are:
      1. for pagespeed:
      Optimize the order of styles and scripts A (100) B (85)
      Remove query strings from static resources A (100) A (90)
      2. for yslow:
      Add Expires headers D (67) B (89)
      Put JavaScript at bottom A (100) A (95)
      3. for timeline:
      12 Requests 19.9 KB 542ms (onload: 549ms)
      11 Requests 19.4 KB 425ms (onload: 429ms)

      1. pagespeed and yslow would prefer donottrack-min.js to be loaded at the bottom of the HTML, but that would mean it wouldn’t be able to filter out script that does get loaded earlier on
      2. pagespeed would like the querystring (the part from the questionmark on in donottrack-min.js?dntver=0.7.2) to be removed, but this is needed to make sure that users don’t get an old version from a cache somewhere when when I push out an upgrade of WP DoNotTrack
      3. yslow is better thanks to the fact that you don’t load the quantcast javascript & image which do not have expires headers
      4. but most important of all: your page loads faster with WP Donottrack (and less requests, smaller total amount of data)
