Hi Amol,

your setup is cross-domain setup (because the client and server protocol+origin+port is not the same). There is a CORS specification (http://www.w3.org/TR/cors/) which says that the OPTIONS request (called also preflight request) MUST work without authorization but your server not respects this. So there are 2 possible solutions:

1.) contact the server developer and ask for fix
2.) use rewrite rules in your web server configuration - for example (for Apache):

RewriteCond %{HTTP:Access-Control-Request-Method} !^$
RewriteRule ^(.*)$ $1 [R=200,L]
