Webservice error 401 returned from webservice called from javascript
<p>I am having a wsdl file in my application server along with swf and javascript. 
We call a javascript method and from Javascript we call webservice using soap. The http request has been sent with credentials. It works fine and we get data for a while and after sometimes it returns 401 error. When we use different valid  credentials. it works fine. Any one help me what went wrong</p>
