Casablanca request returns the same response every time

Question

Hi All,

I have the following code which executes every time when a user press a button:

http_client client = http_client(API_URL);
pplx::task<http::http_response> clientRequest = client.request(methods::GET, L"/do/some/action");
clientRequest.then([=](http_response  clientResponse) {
    std::wstring responseString = clientResponse.extract_wstring();
    http::json::value clientResults(responseString );
       .....
});

"responseString" always  has the same value until I restart the application. I checked my server and it returns different response every time. Does anybody know what is the reason this issue?

Hi,

Are you doing this on Windows 8 / WinRT? If so, the problem is that the underlying HTTP stack is rather aggressive about caching the responses from GET messages. Make sure your server is sending the right cache-control headers in its responses.
