jQuery: I get OPTIONS request instead of GET

Question

I am using simple jQuery

$.get( .... );

Here instead of getting GET response I get OPTIONS.( checked in firebug Net)

Same code is working fine in Safari. Looks like some problem with Firefox.

Any workaround / solutions to fix this problem..

Thanks

The OPTIONS request what you see is the preflight request, you can read about that here:

• https://developer.mozilla.org/En/HTTP_access_control
• http://www.w3.org/TR/cors/
• http://msdn.microsoft.com/en-us/library/cc288060(VS.85).aspx

It's there because you're requesting a cross-domain XMLHttpRequest so the browser has to check whether your request is allowed on the remote server or not.

There are two solutions to solve the problem (as mentioned above):

• implement the response for the OPTIONS request with the corresponding Access-Control-* headers
• use a JSONP request instead of simple JSON
