CachingHttpClient should be able to cache ResponseHandler responses (or the
result of some new form of ResponseHandler)
-----------------------------------------------------------------------------------------------------------------------
Key: HTTPCLIENT-1090
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1090
Project: HttpComponents HttpClient
Issue Type: Improvement
Components: HttpClient
Affects Versions: 4.1.1
Environment: Mac OS X 10.6.7 + Eclipse Helios SR2
Reporter: David Waite
Priority: Minor
When creating a ResponseHandler to parse the response value into a usable java
object, I notice that the code is executed every time, even if the response
object is served from cache. It would be nice to have a system where a
ResponseHandler can be written such that its value is also served from cache.
This may require a different interface which:
- Exposes just the values which are not altered when served from a cache
- Returns objects which can be cached out of process ( through documentation,
and having the return type extend Serializable)
Alternatively, if there is a header uniquely identifying a response, a
WeakHashMap could be used to provide a cache associating a response with a
created object (although such a cache would not correlate to the HTTP cache in
terms of retention)
