Oleg Kalnichevski updated HTTPCLIENT-1240:
------------------------------------------
Fix Version/s: 4.3 Alpha1
The way HttpClient components are wired together is going to change
dramatically in the 4.3 series, so this issue will no longer be applicable.
However, do feel free to submit a patch for the 4.2.x branch.

> Empty HttpParams for cacheable requests
> ---------------------------------------
>
> Key: HTTPCLIENT-1240
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1240
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Cache
> Affects Versions: 4.2.1
> Reporter: Francois-Xavier Bonnet
> Priority: Minor
> Fix For: 4.3 Alpha1
>
>
> With DefaultHttpClient, HttpResponse.getParams() returns a ClientParamsStack
> with all the parameters previously set at HttpClient or HttpRequest level.
> With CachingHttpClient it returns an empty BasicHttpParams when a response is
> cached.
> This feature can be very usefull when you are doing complex processing with
> Interceptors for example. It is described in HttpClient documentation:
> http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html#d5e299
> http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/ClientParamsStack.html
> CachingHttpClient should not break this feature.
> Here is some sample code:
> // Client and Request scoped params with DefaultHttpClient
> DefaultHttpClient httpClient = new DefaultHttpClient();
> httpClient.getParams().setParameter("testClientParam",
> "testClientParam");
> HttpGet httpGet = new
> HttpGet("http://www.google.fr/images/srpr/logo3w.png";);
> httpGet.getParams().setParameter("testRequestParam",
> "testRequestParam");
> HttpResponse response = httpClient.execute(httpGet);
> EntityUtils.consumeQuietly(response.getEntity());
>
> System.out.println(response.getParams().getParameter("testClientParam"));
>
> System.out.println(response.getParams().getParameter("testRequestParam"));
> // Same test with CachingHttpClient
> httpClient = new DefaultHttpClient();
> CachingHttpClient cachingHttpClient = new CachingHttpClient(httpClient);
> cachingHttpClient.getParams().setParameter("testClientParam",
> "testClientParam");
> httpGet = new HttpGet("http://www.google.fr/images/srpr/logo3w.png";);
> httpGet.getParams().setParameter("testRequestParam",
> "testRequestParam");
> response = cachingHttpClient.execute(httpGet);
> EntityUtils.consumeQuietly(response.getEntity());
>
> System.out.println(response.getParams().getParameter("testClientParam"));
>
> System.out.println(response.getParams().getParameter("testRequestParam"));
> If you agree I can provide a patch and unit tests
