Subject [jira] [Commented] (HTTPCLIENT-1240) Empty HttpParams for cacheable requests
Date Mon, 17 Dec 2012 20:40:13 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13534283#comment-13534283

Oleg Kalnichevski commented on HTTPCLIENT-1240:

There is still HTTP context whose primary purpose is to keep contextual details about request
execution such as those that need to be shared by protocol interceptors. One of the problems
with the HttpParams interface is in many ways it overlaps with the HttpContext and there is
no clear distinction between the two.

>                 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
> 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
