JR46279: CMVC 226880 - THE PROBLEM WHERE THE NEW USER AGENT WAS CACHED

APAR status

• Closed as program error.

Error description

• Some of our store pages use user-agent to detect which browsers
  hit the server. The Store acts accordingly depending on the
  browser.\line \line For example, the user-agent checks for the
  following -\line \line 1.  Checks for Android and iOS
  device\line 2.  Checks for IE6 for unsupported browser
  issue\line 3.  Checks for IE7 and IE8 for bazaar voice.\line
  \line However, the current check for user-agent is in JSP level
  and when caching is turned on for that specific page, it will
  actually be cached.  This means the store page will not display
  correctly on certain browsers depending on the page that has
  been cached.
  

Local fix

• The only workaround is to turn off caching so that the user
  agent will not be cache.
  

Problem summary

• USERS AFFECTED:
   WebSphere Commerce users on v7.0 who use IE6, iOS and Android
  devices
  
   PROBLEM ABSTRACT:
   JSP level User-Agent cached value is used in the store. As a
  result, if cache is enabled the wrong page will be displayed for
  different devices.
  
   BUSINESS IMPACT:
   Store page will not be display correctly on certain browsers
  depending on the page that has been cached.  For example.
  
   When cache is enabled and empty initially, and someone uses IE6
  to hit the store, the page will be cached.  Afterwards, all user
  who hit the store page regardless of the browser will see the
  Unsupported browser error.
  
   Similar situation for iOS specific code.
  
   RECOMMENDATION:
   The way to solve this problem is to use JavaScript to detect
  the user-agent instead.
  

Problem conclusion

• In the code, search for "header['User-Agent']", which is the a
  JSP code to check user-agent, instead, use the javscript object
  "navigator.userAgent" to check.
