AllowAnyOrigin allows any origin. The way to add the header depends on the apps code language.
Changing the code is the least recommended option because it requires the most effort.
Access control allow origin 2 domains. Limiting the possible Access-Control-Allow-Origin values to a set of allowed origins requires code on the server side to check the value of the Origin request header compare that to a list of allowed origins and then if the Origin value is in the list to set the Access-Control-Allow-Origin value to the same value as the Origin value. Extend the lifetime of the access token. If the server allows the request it sets the Access-Control-Allow-Origin header.
Can make your APIwebsite vulnerable to cross-site request forgery CSRF attacks. Web Fonts for cross-domain font usage in font-face within CSS so that servers can deploy TrueType fonts that can only be cross-site loaded and used by web sites that are permitted to do so. Besides specifying a single domain only is another valid option which would allow access from everywhere.

Its very simple to solve if you are using PHPJust add the following script in the beginning of your PHP page which handles the request. There is no possibility for the Access-Control-Allow-Origin header to contain multiple domains like separating different domains via spaces or comma.
If you have multiple domains and want to set a CORS header based on that domain you can use a cool hack like this. As you can see the Origin header contains exactly the origin domainprotocolport without a path. The value of this header either matches the Origin header or is the wildcard value meaning that any origin is allowed.
Add code to your globalasmx and have it check if that origin is in a defined list in your codeconfig. To implement what you need then the following nginx snippet will check the incoming Origin header. Add a URL Rewrite Inbound Rule to capture the Origin header.
It means the browser has a property called Access-Control-Allow-Origin which restricts the requests from different domains for security purposes. If AllowAnyOrigin is called the Access-Control-Allow-Origin. Use URL Rewrite to check for the domain and add it to the origin.
Header Set Access-Control-Allow-Origin But as mentioned above its safer to actually set the Access-Control-Allow-Origin to contain the list of domains that your application can request data from or send data to. This cross-origin sharing standard can enable cross-site HTTP requests for. The server can inspect the Origin and if it agrees to accept such a request add a special header Access-Control-Allow-Origin to the response.
Simply activate the add-on and perform the request. Navigate to your site and click URL Rewrite. This is obviously something that the Same Origin Policy normally prevent.

You can change your app to support CORS by adding the Access-Control-Allow-Origin header with appropriate values. Invocations of the XMLHttpRequest or Fetch APIs as discussed above. Access-Control-Allow-Origin lets you easily perform cross-domain Ajax requests in web applications.
The Origin header gives the domain of the site that is making the request. So we need to enable CORS to accomplish the request. The W3 spec on Access-Control-Allow-Origin explains that multiple origins can be specified by a space-separated list.
In practice though this is unlikely to be interpreted correctly by current implementations in browsers eg fails for Firefox 45 at time of writing. Enter the following values. CORS error in browser.
In the preceding Response headers the server sets the Access-Control-Allow-Origin header in the response. Then dynamically add that domain to the Access-Control-Allow-Origin header. I suppose the server looks at the origin header of a request and then decides whether to allow request or not.
