如何解决“拒绝设置不安全标头：连接”？

Question

I'm using Prototype combined with CodeIgniter to submit an AJAX request. My browser is Chrome. I'm receiving an error in the console that reads "Refused to set Unsafe Header: Connection". Here is the Ajax Request line:

new Ajax.Request('/vbs/index.php/signup/get_ratecenters',{method:'POST', evalScripts:true})

I've attempted to set the type to synchronous, but received the same error.

Can someone assist? Thanks in advance.

What happens if you load /vbs/index.php/signup/get_ratecenters directly in your browser?

I read somewhere online that "Refused to set Unsafe Header: Connection" is a warning that the HTTP "Connection" header cannot be set, but doesn't mean the request will not be processed, so it's possible something else is going on here?

Check /vbs/index.php/signup/get_ratecenters and make sure it returns valid JavaScript code. Execute that code in the Chrome console and make sure it is error free... possibly here's a different error here.
