    Hi,

    I've just upgraded to v2 of Kendo UI and I plan to use the grid, window and possibly the splitters in an html5 Amazon Cloudfront app.

    The problem I encountered with v.1 was that I could not just use the grid and windows scripts as my grid & window would not render.

    At that point I tried every combo of the separated (smaller) scripts and finally came to the conclusion I need the "all" script to have beta 1 function.

    That script is 250k which is very expensive in terms of bandwidth for my architecture.

    So I googled on CDN and I found a blog post on the kendo site with links to the cdn for beta 1 in an article. However I found no "official" discussion of the kendo CDN as exists on the Telerik site for example (I am a Telerik Ajax/Silverlight user for almost 3 years).

    The CDN worked fine but I had some grid issues and I decided to upgrade to beta 2. It works for my grid but my windows are now transparent so I just downloaded the v2 beta to see what is going on. I use JQuery UI and it is possible it is my own doing that the background on my windows are all "transparent" in v. 2.

    However the major concern is CDN. I am going to re-evaluate if just links to the grid & window scripts do the trick with v2 but what would be best is a commitment by Kendo to support the CDN :))

    Further my additional concern was if I go live before Kendo is officially release and the beta CDNs exist would they be taken down one day causing my app to break? I need something that won't change in terms of CDN so that I can hotlink and forget about.

    That's about it :))

    I applaud your suite as this was something I believed was necessary in the industry for quite some time.

    Cary

    Hello Cary,

    However I found no "official" discussion of the kendo CDN
    > We officially release our scripts and styles on a CDN with each official release, and we always use the CDN for our online demos. Indeed, we don't mention that in the documentation - we'll address this for the release.

    At that point I tried every combo of the separated (smaller) scripts and finally came to the conclusion I need the "all" script to have beta 1 function.
    > With the official release, we'll be providing a download builder that will select the dependencies you need, so there will be no more guesswork.

    ... what would be best is a commitment by Kendo to support the CDN
    > We support the CDN, as stated above. Please note that the CDN is released only with official releases (plus SPs and betas), so it's highly recommended that you try it out (i.e. with a beta) before the official release -- this way we'll have time to address issues that might pop up -- otherwise you'll have to wait for a new release.

    ... would they be taken down one day causing my app to break?
    > No, that would be pointless. The CDNs are there to stay (you can access the MVC CDN from Q1.2010, for example). Plus, the CDNs are priced per request&transfer, so there's no additional cost for us in maintaining old files there. Even if the pricing was per storage, the minified files are too small to induce a cost.

    Best,

    Thanks for your excellent answers Alex! This is why Telerik is my favorite software company of all time! :))
