No cache with HttpClient in Windows Phone 8

Question

I\'ve read that in order to disable caching while using get and post methods in HttpClient, I need to use a WebRequestHandler as my HttpClien

Answer 1

I found 3 ways

1. Add a random Query String to the end of your URI (think Guid.NewGuid()) this will avoid caching on the client as the Query String will be different each time

string uri = "http://host.com/path?cache=" + Guid.NewGuid().ToString();

2. Specify no cache in the OutgoingResponse header within your WCF service operation:

var __request = (HttpWebRequest)WebRequest.Create(url.ToString());
if (__request.Headers == null)
    __request.Headers = new WebHeaderCollection();
__request.Headers.Add("Cache-Control", "no-cache");

3. markup your service operation with the AspNetCacheProfile attribute:

[AspNetCacheProfile("GetContent")]  
public ResultABC GetContent(string abc)  
{  
  __request = (HttpWebRequest)WebRequest.Create(abc);
  return __request;  
}

And update your web.config

  
  
       
        
           
               
           
      
  
...
