Hi,

I am trying to pass UserToken (authentication token) in ajax call for ASP.WEB API service call.
I am getting below error message.

XMLHttpRequest cannot load http://localhost:7532/api/Common/GenerateTabs?clickedTab=null&null&_=1407319841857. Request header field UserToken is not allowed by Access-Control-Allow-Headers.

without authentication token in request header i am getting expected result.

JQuery Code
function InvokeService(url, type, successCallBack, data) {
$.ajax({
cache: false,
type: type,
url: url,
data: JSON.stringify(data),
async: false,
crossDomain: true,
headers: { 'UserToken': 'sdsdds' },
success: successCallBack
});
}

Controller
[EnableCors("*", "*", "*")]
public class CommonController : ApiController

Please help me on this.

I have done changes as per your suggestion.

now i am getting below error.

XMLHttpRequest cannot load http://localhost:7532/api/Common/GenerateTabs?clickedTab=null&null&_=1407325018374. The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Origin 'http://localhost:38501' is therefore not allowed access.

Header is
Remote Address:::1:62649

It's as it seems. On the target server the Access-Control-Allow-Headers does not contain a header key of UserToken...
You have to include it to enable its use...
