Forum:Access to nocookie.net needed to view/edit Comments ??

Why is it necessary to enable access to a site called nocookie.net to view and edit Comments ?

This seems to be a recent change.


 * Lots of Wikia stuff is on nocookie.net, most importantly all the uploaded images.--PedroM (talk) 09:43, August 27, 2012 (UTC)


 * CSS and JavaScript as well, which is probably why comments need it. nocookie.net is just a cookieless domain to serve static content, there's no real reason to block it. - Tjcool007 (Wall) 09:57, August 27, 2012 (UTC)


 * It's running scripts from outside of the wikia.com domain, it should be blocked, along with all the other tracking/spying/advertising sites.
 * Not all external sites are inherently evil. Javascript libraries like jQuery are loaded from ajax.googleapis.net by many websites to exploit the caching, and Wikia does most of its noncontent hosting on nocookie.net. We're talking about a company that has a large global CDN&mdash;such cases should not be purged. TK-999 (talk) 18:56, August 27, 2012 (UTC)


 * I don't know what a 'global CDN' is, but I doubt if it's an excuse to create valid security risks by blindly allowing scripts to run from external sites. I expect this discussion will go no where since most site managers these days seem to ignore security concerns in favor of traffic.


 * What "security concerns"? Your concerns don't make any sense. Wikia gets a lot of traffic, to deal with that you need a lot of servers. More importantly, you need a lot of servers in the same countries as your users to minimise international traffic (which is slow). Companies that run server farms in multiple countries are called "Content Delivery Networks".
 * I believe "a little bit of misapplied knowledge is more dangerous than ignorance" is at work here. If Wikia didn't use a CDN then the whole site would be slower. Wikia might actually save money by not doing this but it would suck for all of us. [Hint: Those scripts coming in from nocookie were written by Wikia, just because they are on a different domain does not mean Wikia did not write them] Lunarity 03:45, August 28, 2012 (UTC)


 * Wikia delivers all static content - images, stylesheets and scripts - from nocookie.net. The name tells you the reason why they do that already. Your computer sends a whole bunch of cookies to wikia.com with every request. All those static files can be delivered without the cookies, but the only way to tell your computer not to send them, is to serve them from a domain other than wikia.com. Dropping the cookies makes your computer's requests to Wikia faster - simply because they're smaller. There's a secondary benefit too: browsers tend to limit the number of downloads per domain, so spreading data across domains increases overall download speed as well.


 * Wikia follows the advice of the great web performance gurus here. If you want you can test Wikia pages yourself with Yslow or Pagespeed. Both tools give Wikia near-perfect performance scores.
