Error description
DynaCache can not different request types which cause error
Local fix
No work around.
Problem summary
****************************************************************
* USERS AFFECTED: Any user of WebSphere Application Server *
* v5.0.2 who uses dynamic cache to cache *
* servlet or jsp responses based on the HTTP *
* request methods (GET, POST etc). *
****************************************************************
* PROBLEM DESCRIPTION: Dynamic cache does not differentiate *
* between HTTP request methods. This *
* causes it to return incorrect *
* responses. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Dynamic cache does not differentiate between HTTP request
methods like GET, POST etc. So if a GET request comes in for a
servlet first and its response is cached, and a HEAD request
comes in later for the same servlet, dynacache returns the GET
response for HEAD request.
Problem conclusion
The above described behaviour is incorrect. After applying
this fix dynacache should start differentiating between
different request methods. A new component type called
'requestType' has been introduced which allows caching based
on the HTTP request method. If the cache policy is not based
on the 'requestType', then the request type information is
appended to the cache id for GET and POST requests and all
requests with request types other than GET and POST are made
uncacheable.
