Refresh image in CDN immediately after upload to S3 with same file name
amazon-web-services,cdn,amazon-cloudfront
You'd want to store a count of how many times it has been changed and use something like <userId>.jpg?v=2 on your site. You'd have to turn query strings on for the CloudFront distribution. Without a filename change or query string change, you'd have to use a CloudFront invalidation, which will...
Windows azure CDN blob transactions bill
In answer to your first question, you will be billed for the second request for the image, but the cost will be minimal (from here): Any HTTP(S) request that terminates at the CDN is a billable event. This includes all response types, success, failure, or other. However, different responses may...
Run script during HTTP request
It seems to me that what you are trying to do is essentially have servers load files from one primary server. I would recommend not running a script but using the CDN servers as proxies which cache the responses. You would have to setup something like this in your apache...
Sitecore Media Library & Azure CDN

If you are using Azure PaaS and making use of WebRoles (such as when using the Sitecore Azure Module) then you should be able to more easily integrate the cloud service with Azure CDN. I'm not sure exactly what your plans were with integrating with Azure, but rather than worrying...
When choosing the domain name for a CDN, is there anything to be aware of? [closed]
For a CDN, latency is king. The length of the domain label or the TLD you choose will not matter, because TLDs are supported by the low-latency network of DNS root servers. What will matter, though, are the authoritative DNS servers for your domain. Slow responding authoritative servers will increase...
How to wait for document.write to complete

Rails 4 carrierwave default_url not using cdn

I fixed it using what I had thought about doing. And that is prepending the CDN url during prod and staging env. def default_url if !(Rails.env.development? || Rails.env.test?)

How to use Sementic UI cdn

You would need to use a task that first downloads the resource and then concats. But that begs the question, why use a CDN script? CDNs are generally used for common resources that a client might already have cached. If you concat the file, you're no longer taking advantage of...
Why does CDN work, but a relative link does not?
The CSS file refers to font files using relative URLs. So when you copy the CSS, you also have to copy the font folder to MyProject/font-awesome/fonts. Basically, when you download the Font Awesome ZIP file, you should extract the entire thing into MyProject/font-awesome. This will get you the all the...
parser.js not found on Google CDN for dojo 1.10.3

Enable/Disable PHP on Nginx for CDN
PHP with nginx is very different than PHP with Apache, since there is no mod_php equiv for nginx (AFAIK). PHP is handled by totally separate daemon (php-fpm, or by passing the request to an apache server, etc.) As a result, you can bypass php completely simply by letting nginx handle...
Why do links not show the http protocol (ex. CDN links)?
That means that the link will use the same protocol that the page where the link is placed is using. If the link is in a "http://" page, it will use "http://" to open the link. If otherwise it is in a "https://" page, it will use "https://" to open...

Does CDN know which website the client is visiting when fetching jquery.min.js or other resource from CDN?
Yes, they can use the referer header field: The HTTP referer (originally a misspelling of referrer) is an HTTP header field that identifies the address of the webpage (i.e. the URI or IRI) that linked to the resource being requested. By checking the referrer, the new webpage can see where...

What happen when user location is near the Origin server more than CDN server?
If you switch to using a CDN, then all your users will go through the CDN. If they don't have a server near you, then it is going to be slower for your local users. It's up to you to make a call on whether that tradeoff is worth it...
With GoDaddy (or other registras) can I point a CNAME to an index.html file on a CDN or Azure blob?
Right now this is not possible because Azure Blob Storage still does not support default document concept (Amazon S3 does). Thus while you can do a CNAME mapping but you can't point to pick index.html file when somebody types in your domain name.

Bootstrap CDN classes conflict?

Are CDNs that don't cache useful?

I would say the answer is...it depends. I appreciate that isn't very useful so I'll expand. If you're writing an internal (intranet) application it would be better, and more efficient, to bundle the framework into your app. Your users will then only need to pull files from the local network....
