No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '...' is therefore not allowed access
ajax, cors, javascript, jquery, xmlhttprequest
Solution
Use `addHeader` Instead of using `setHeader` method,
response.addHeader("Access-Control-Allow-Origin", "*");
`*` in above line will allow `access to all domains`.
For allowing `access to specific domain only`:
response.addHeader("Access-Control-Allow-Origin", "http://www.example.com");

Problem
I'm using .htaccess to rewrite urls and I used html base tag in order to make it work. Now, when I try to make an ajax request I get the following error: XMLHttpRequest cannot load `http://www.example.com/login.php`. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '`http://example.com`' is therefore not allowed access.
