Refused to set unsafe header “Connection”

问题

I am working on a cross platform application that targets Android and iOS platforms. I am using jQuery 1.9.1, Jquery Mobile 1.3.1 and Phonegap 2.8.0.

I want to send an ajax request and set the request headers "Connection" and "Keep-Alive". On Android Phones with OS greater than 4.1 (Whose default browser is Chrome) I get an error which says "Refused to set unsafe header "Connection"".

I am able to send such requests on lower end devices and even on iPhones.

Can Anyone Please help me out.

I have to set these 2 headers in the request.

Thanks in advance.

回答1:

Section 4.6.2 of the W3C XMLHttpRequest Level 1 spec lists headers that "are controlled by the user agent" and not allowed to be set with the setRequestHeader() method. Both Connection and Keep-Alive are in that list.
