will be helpful for those in need Well I asked a similar question on regards of how to work with caching data downloading and performing them in parallel. Take a look at the answer here: Task caching when performing Tasks in parallel with WhenAll
So in short your GetImage should go in a list that holds the tasks instead of the result.

Caching using Axis 1.4 + web service response caching at client side

Caching using Axis 1.4 + web service response caching at client side

I wish this help you Instead of caching the XML response, you might be better off using EHCache to cache whatever objects you're creating as a result of the web servcie call.
If it's a matter of performance (i.e., your web service takes seconds to reply), then caching is a good idea. Nearly all of the AXIS webservices I've created ran sub-second, so caching may not be desireable or necessary in that instance.

will help you I have created an ashx file to generate image thumbnails on the fly. I would like to cache these images client side after they are called the first time. , Surely this line:
code :
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Server);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);

          if (statusCode == 200) {
              // Server response
              responseString = EntityUtils.toString(r_entity);
          } else {
              responseString = "Error occurred! Http Status Code: "
                      + statusCode;
          }           } catch (ClientProtocolException e) {

HttpClient is caching requests to the same URL

I hope this helps you . I assume you are setting the cache-control header to no-cache? client.DefaultRequestHeaders.CacheControl.NoCache = true;
If so but it still doesn't work - maybe the server is caching the response? If it comes down to it, you can usually defeat something like that by adding a cachebuster to the querystring though. Just append a bogus param and pass it a unique value each time. For example, if your URL is http://my.url.com/resource/someid then you can defeat the caching by using http://my.url.com/resource/someid?b=1 and then increment that "b" param with each call.

seems to work fine I've had a similar problem (see Safari Caching GET request even with disabled cache). Adding Vary: * forced Safari to stop caching. Nothing else worked, including Vary: Cookie even though cookies changed between requests.
