AJAX Anonymous Webservice Call

Hi All,

I have a use case where I need to send a webservice request anonymously to a server .

My browser is having a active session of a user details but the user is not present in the server where I am firing the webservice request .

So Now when I send the webservice request to the server the server is validating the user as it has a valid session and throwing a 401 error back .

What I need is , to fire the webservice request with anonymous so that the webserver wont receive the active session details and not validate the session user for permissions ..etc

Can Some one help me in do this .
