Abstract:  Dynacache stores cookies as part of the response by default unless configured otherwise on a per request basis in cachespec.xml. So there is a risk of sharing cookies between users

Description/symptom of problem:  
PK19485 resolves the following problem:

ERROR DESCRIPTION:                                              
 The customer accidentally enabled caching of the cookies in the
cachespec.xml for websphere commerce and caused WebSphere       
Commerce shoppers were seeing other shoppers                    
personal information. They want that the store-cookies property 
moved out of the cachespec.xml for websphere commerce.          

LOCAL FIX:                                                      
None.                                                           

PROBLEM SUMMARY

USERS AFFECTED:
All users of WebSphere Application Server
using the servlet caching feature

PROBLEM DESCRIPTION:
Dynacache stores cookies as part of
the response by default unless
configured otherwise on a per request
basis in cachespec.xml. So there is a
risk of sharing cookies between users
which violates security.

RECOMMENDATION:
None

Dynacache stores cookies as part of the response by default
unless configured otherwise on a per request basis in
cachespec.xml. So there is a risk of sharing cookies between
users which violates security.This apar provides ability to
disable storing cookies globally on a per server basis via
custom property
"com.ibm.ws.cache.CacheConfig.disableStoreCookies"

PROBLEM CONCLUSION:                                             
This apar provides the ability to disable storing cookies       
globally on a per server basis.                                 
                                                                
The fix for this APAR is currently targeted for inclusion       
in cumulative fix 5.1.1.10 and fixpack 6.0.2.9.
