cdn

My site uses several common CDN hosted resources, like bootstrap.css , jquery.js and fontawesome.css . Is it possible to get information, probably with JavaScript, do my site visitors have warm caches for these resources in their web browsers? While not an answer, some interesting insight I found when working on this problem with Chrome : Fetching the resource from CDN is a deferred call, while fetching an item from the cache seems in fact to be a blocking call, despite being quite fast. Firefox didn't seem to this exhibit behavior consistently (and I didn't even bother with IE). To test this

I am having an issue with HTML injection into an already loaded DOM where the inline javascript is being loaded after the script file is downloaded. From what I know this should not be async and the inline script should execute after the script file. This works if the domain name is the same as the calling page, but using a CDN or even a subdomain does the same thing. Is there something I should do to rework how I am calling these? I swear this worked before as I had the CDN on for over a week but maybe I never caught this issue. Console Loading Inline Script VM1400:3 Uncaught TypeError:

EDITED to clarify: In terms of performance (though that's still a wild term, I know), which is better - loading a local version, or a CDN version of jQuery, over RequireJS? For the record, RequireJS online doc contains some passage that seems to discourage CDN using, though I am not really sure 100% about what it means: Do not mix CDN loading with shim config in a build. Example scenario: you load jQuery from the CDN but use the shim config to load something like the stock version of Backbone that depends on jQuery. When you do the build, be sure to inline jQuery in the built file and do not

I have single page app built with Backbone.js. I host app (app consists of static files only) on Amazon S3. I use CloudFront as a Bucket CDN. App is accessed by https://myapp.com -> https://abcdefgh34545.cloudfront.com -> https://myBucket.s3-eu-west-1.amazonaws.com/index.html How I can use Prerender.io service with this stack? I have to somehow detect that WebSpider/WebRobot is accessing the page and redirect it to prerender.io... It's hard to use Prerender.io with a static Amazon S3 site. You could stand up an nginx/apache server in front of s3: https://myapp.com -> https://mynginx-server.com

I am trying to use the Ace code editor library ( http://ace.ajax.org/ ), but im having trouble. According to the embedding guide, this should load the required js files from Amazons CDN. <script src="http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js" type="text/javascript" charset="utf-8"></script> However it fails, in Chromes console it shows: Could not load worker ace.js:1 DOMException {message: "SecurityError: DOM Exception 18", name: "SecurityError", code: 18, stack: "Error: An attempt was made to break through the se…cloudfront.net/src-min-noconflict/ace.js:1:76296)", INDEX

I want to use Cloudfront to serve images and CSS from my static website. I have read countless articles showing how to set it up with Amazon S3 but I would like to just host the files on my host and use cloud front to speed up delivery of said files, I'm just unsure on how to go about it. So far I have created a distribution on CloudFront with my Origin Domain and CName and deployed it. Origin Domain: example.me CName media.example.me I added the CNAME for my domain: media.mydomain.com with destination xxxxxx.cloudfront.net Now this is where I'm stuck? Do I need to update the links in my HTML

I have a website with only home page available through simple HTTP protocol. All other pages are accessible only through HTTP over SSL(https://). I'm using CDN for home page and very happy with it. But for me it looks like using CDN for https pages is impossible because of security warnings, especially in IE. My files hosted at CDN are accessible though simple HTTP protocol. What should I do? How this problem can be solved? You need to get a CDN that supports serving files over HTTPS, then use that CDN for the SSL requests. You can do this if their boxes have HTTPS support. What you can't do
