Check your max URL length setting: 

Application Security -> File Types -> Allowed File Types

It's either 

.jsp
or 
*
File Type that matches for this request. Increase the URL length value as needed.

This should solve your problem.

Kindly check the header /XXXXX/login.js/login.js/login.js/login.js/login.js/login.js/login.js/login.js/login.js/login.js/login.js/common/logout.jsp? It looks suspicious. It is application error but please tell why it is occurred?
