Description

1:When I use ugsync for LDAP data synchronization, I find that the API has errors for some reason. At this time, the API will return 404, and then the client side will clear the sessionid, resulting in 401 errors in subsequent synchronization cycles. 
2:the first use cookie call api,then will   cookieClient.removeAllFilters();
The code is as follows:
protected WebResource createWebResourceForCookieAuth(int currentIndex, String relativeURL) { Client cookieClient = getClient(); cookieClient.removeAllFilters(); WebResource ret = cookieClient.resource(configuredURLs.get(currentIndex) + relativeURL); return ret; } 
 3:then the next time have some error ,then the next time there not have cookie ,then connect will response 401 ,because cookieClient  have not any filter ,contain httpBasicAuthFilter(username,password).
4:Then I load httpbasicauthfilter every time before using it.
