Local fix
Problem summary
USERS AFFECTED: WebSphere Commerce users on v7.0 PROBLEM ABSTRACT: A null User-Agent header from an HTTP request causes a NullPointerException BUSINESS IMPACT: Not able to access the store when the User-Agent in the HTTP header of a request is null RECOMMENDATION:
Problem conclusion
The problem happens when WebSphere Commerce is trying to perform device mapping lookup and observes the null user-agent string. The fix is to check if the user agent is null, and if so, do not perform the device mapping lookup. ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
