response-headers

I'm having troubles with collecting json values from a URL in my application. When I try to get them a error log is displayed in the console saying that origin is not allowed by access-control-allow-origin. I researched a bit and found out that response headers have to be set to Access-Control-Allow-Origin: * How can I do that using pure javascript? No jquery or any other library.

I am trying to filter some url pattern to caching. What I have attempted is put some codes into WebSecurityConfigurerAdapter implementation. @Override protected void configure(HttpSecurity http) throws Exception { initSecurityConfigService(); // For cache http.headers().defaultsDisabled() .cacheControl() .and().frameOptions(); securityConfigService.configure(http,this); } However this code will effect all of the web application. How can I apply this to certain URL or Content-Type like images . I have already tried with RegexRequestMatcher , but it does not work for me. // For cache http

There are a lot of question with my issue but, I tried some of the solution and no one worked.
