问题
I've encountered that this does not work on multiple files when working with cross-domain. Anyone have any reason or am I doing something wrong? I was able to have it work on one PHP file (mydomain.com/file1.php) that I'm accessing from another domain (hisdomain.com). When I tried to access another PHP (mydomain.com/file2.php) from the same domain (hisdomain.com), it won't let me access my scripts in file2.php, because I already have
header("Access-Control-Allow-Origin: *");
in file1.php. Is this coincidence? Should this not be the problem?
However, these files is in an actual hosting site. (e.g. mydomain.com). When I tried working in localhost (http://127.0.0.1/file1.php and http://127.0.0.1/file2.php) with hisdomain.com, file1.php and file2.php was working correctly with both having
header("Access-Control-Allow-Origin: *");
