-------------------------------
Summary: JCacheFilter code logic error
Key: JCS-140
URL: https://issues.apache.org/jira/browse/JCS-140
Project: Commons JCS
Issue Type: Bug
Reporter: liangjiarui
final PageKey key = new PageKey(key(servletRequest), gzip);
Page page = cache.get(key);
if (page == null)
{
....
}
if (page.status == SC_OK) {
checkResponse(httpServletResponse);
the last line always throw exception for the first time the specified url is
requested,because the response is commited in the previous if.
I think the logic of doFilter should be like this:
String key=getKeyFromRequest();
Page page=cache.get(key);
if(page==null){
chain.doFilter();
cache.put(key,response);
}else{
response.write(cache);
}
