jQuery issue on checkout page

Hi,

First of all, let me thank you for the great application!

I've installed it onto my server and noticed a small bug.
It's not in OpenCart, but it is easy to fix

The error occures on nginx webservers when a user tries to check out.
What happens is nginx 'chokes on a empty POST request'.

The sulotions are:
- change from POST to GET (I haven't tried it)
- add a dummy parameter (I added data: 'dummy')

A discussion about this: http://www.ruby-forum.com/topic/160685
Again, this only occures in nginx server, with apache I don't have this issue.

Hope it helps
Daniel

You might want to open a bug in the issue tracking:

Other than that, you might want to contact the nginx guys too since it appears to be mostly a bug on their end, even though doing an ajax POST with no data is not necessary.
