cdn

问题 We have a mediawiki with lots of images http://bbref.com/bullpen/ and want to serve images via our CDN for obvious reasons, but I can't quite grok how to set things up in mediawiki so that we can get img src="/local/path/to/image.png" to output as img src="http://cdn.example.com/local/path/to/image.png" The CDN is up and running, so I don't need any help there. I just need the fix for mediawiki to change image srcs to point there rather than with a relative link. thanks, sean 回答1: Take a look

问题 I'm working on a Java site (jQuery, Wicket, Maven, Spring, Hibernate) and we have just started using a CDN to serve static files on our production server. We use a placeholder for the CDN domain, and have added it to every static file that references a static file. The placeholder gets replaced by Maven through properties filters with Maven. So, for every static file served by the CDN, we have something like this: <img src="${placeholder}/images/dogs/rex.jpg"/> For production, ${placeholder}

问题 I'm working on "CDN" video delivery script. my problem is not all providers are included, therefor I need to check if the client can access the link, if not send him another one. i've tried with get_headers, but with get_headers only the server checks if it can access the link, not the user. $header = get_headers($VIDEO); preg_match('/\d{3}/', $header[0], $code); if($code[0] < 400){ header("Content-type: video/x-flv"); header("Location:" . $VIDEO . $dop); }else{ header("Content-type: video/x

问题 I have a symfony application that gets served by a cdn (eg. akamai) and I generate the asset url on the templates with: {{ asset('myJs.js') }} When I do I want to generate a url like (supposing that the site is served by www.example.com ) : www.example.com/myJs.js?v=321321312312 Where the v parameter get a deployed version in order to force cdn (eg. akamai network) to cache me newer version. Is it a good way to dynamically generate the v parameter? 回答1: If you want to append a hash to the

问题 I am having a strange problem which seems to be a problem of ipv6 vs ipv4 dns names. I have a real time scraper which runs on my server which runs on ipv6 network. After scraping, this scraper returns some urls to images on a web page via ajax calls and then the images are shown in the browser on my local machine via the links returned by the scraper. But these urls are not resolved on my local network. My local machine does not run on ipv6 network. Also the web page being scraped hosts the

问题 I have setup some static content in a CDN but when accessing the .html file, the file gets downloaded and not rendered in the browser. I am using a blob container http://cdn-dezelo-consulting01.azureedge.net/index.html I don't know what I missed ? 回答1: I traced the request/response through Fiddler and noticed the Content-Type property on your blob ( index.html ) is set as application/octet-stream (which is default content type for a blob in Azure). This is the reason it is being downloaded

问题 Should I minify/gzip my Jquery with my other scripts on my page, or use Google CDN for Jquery & JQuery UI and gzip my own stuff. From what I can see its more likely to be faster to deliver from Google and there is a better chance the files will be cached already on the users machine, however its a couple of extra http request and at least I know it will always be available. 回答1: You got it right. For widely-used librairies, using Google CDN is a good idea: uses less bandwith on your server

问题 I currently use Akamai as a CDN for my app, which is served over multiple subdomains. I recently realized that Akamai is caching CORS requests the same, regardless of the origin from which they were requested. This of course causes clients that make requests with a different Origin than the cached response to fail (since they have a different response header for Access-Control-Allow-Origin than they should) Many suggest supplying the Vary: Origin request header to avoid this issue, but

问题 All the assets except for the fonts load nicely, and whenever I go to my site I keep getting messages like this one: Access to Font at 'https://xxxxxxxxxx.cloudfront.net/assets/fontawesome-webfont.woff2' from origin 'https://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://example.com' is therefore not allowed access. As you can see CURL command indicates that no headers are present. curl -H "Origin:
