7.0.0-WS-WCServer-FP009

APAR status

• Closed as new function.

Error description

• The DynaCacheFilterMappings component provides configuration
  settings to specify certain request attributes be added to
  HttpServletRequest objects.  However, it does not allow custom
  code to determine the attribute values to be added.

Problem summary

• USERS AFFECTED:
  Users attempting to implement cache policies using custom
  attributes.
  
  PROBLEM ABSTRACT:
  This fix is to allow custom code to add request attributes for
  servlet caching.
  
  BUSINESS IMPACT:
  Implementation is not possible without the ifix.
  
  RECOMMENDATION:
  

Problem conclusion

• The DynaCacheFilterMappings component tag in the wc-server.xml
  instance configuration file provides a property that defines
  several <map> tags.  Each <map> tag defines how a request
  attribute can be added to the HttpServletRequest object.
  
  This fix allows custom code to be configured using a <map> tag.
  Each <map> tag can specify the following attributes:
  
  className - specify the fully qualified java class name of the
  class that provides a static method that can be called to
  determine the attribute value.
  
  dynacacheAttributeName - specify the name of the attribute to be
  added to the HttpServletRequest object.
  
  methodName - specify the name of a static method of the class
  specified by the className attribute.  The static method should
  return a java.lang.String and accepts the following parameters:
  
  javax.servlet.http.HttpServletRequest - the request object
  com.ibm.commerce.command.CommandContext - the command context
  for this request
  java.lang.String - the name of the attribute (the value of the
  dynacacheAttributeName <map> configuration attribute)
  
  When the returned String value is not null and is not empty, it
  is added to the HttpServletRequest using the setAttribute
  method.
  
  For example, to call the
  MyClass.getMyAttributeValue(HttpServletRequest, CommandContext,
  String) method to add an attribute named "MyAttribute" to the
  request object, specify the following <map> tag:
  
                  <map
                      className="com.mycompany.MyClass"
                      display="false"
  dynacacheAttributeName="MyAttribute"
                      methodName="getMyAttributeValue"
  name="getMyAttributeValue"/>
