Content-Type is repeated when using dojo.xhr

[Randy Hudson]

Here's a snippet showing the bug:

var args = {

url: '/foo', headers: {'content-type': 'text/plain'}

}; dojo.xhrGet(args); args.url = '/bar'; dojo.xhrGet(args);

In the second call to xhrGet, the outgoing request has header:

content-type:text/plain, text/plain

The first call to xhrGet is corrupting the args, causing the second call to have the problem.

Here's the problematic code in xhr.js:

if(hdr.toLowerCase() === "content-type" && !args.contentType){

args.contentType = args.headers[hdr];

A variable should be used instead of modifying the caller's args.

This was fixed when dojo/request was written.
