I'm making a web-based tool that makes a web request to a CSV file at https://wikistats.wmflabs.org — however, because that webserver hasn't enabled CORS (cross-origin resource sharing), most browsers can't fetch the file. To see this, open your browser to any non-WMFlabs.org URL (like github.com), then open the JavaScript Console, and type in the following: ``` fetch('https://wikistats.wmflabs.org/api.php?action=dump&table=wikipedias&format=csv').then(res => res.json()).then(x=>console.log(x)) ``` Firefox for example will tell you, "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://wikistats.wmflabs.org/api.php?action=dump&table=wikipedias&format=csv. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). TypeError: NetworkError when attempting to fetch resource." Assuming Wikistats, the Cloud team, and the Wikimedia Foundation *do* indeed want this data to be loadable by JavaScript running on any domain, the standard way to fix this is to add the "Access-Control-Allow-Origin: *" header to all responses sent by the webserver.
