问题
I use RestSharp in my Windows Phone 7.1 project.
My problem is RestSharp always cache response data.
Example:
At the first time I send request, it returns data correctly. After some delete operations, I send that request again, but response seems the same as the first time, nothing's changed.
If I stop debugging and press F5 to start again, it works perfectly as expected.
I also tried request.AddParameter("cache-control", "no-cache", ParameterType.HttpHeader); and got no luck.
How can I fix this problem?
回答1:
I have the same issue so just add header that specify not to cache response data client is my RestClient with base url and than add default header Cache-Control with value no-cache.
client.AddDefaultHeader("Cache-Control", "no-cache")

I found solution in Rico Suter comment, thanks! I will mark this as accepted anwser
its a hack but try something like url = originalUrl + "&nocache=" + DateTime.Now.Ticks

The "Cache-Control" header should do the trick!
I think HTTP Headers are case-insensitive, but the server may not agree with me there! You should try using Cache-Control instead of cache-control...
Also, I would also add the Pragma header with no-cache value to the request (some old servers don't use the "Cache-Control" header, but they will sure recognize this one)!
And I would try to use Fiddler to debug the comms and check that the headers are really being sent to the server as expected!

Another solution can be to set the "If-Modified-Since" header with value of DateTime.Now:
client.AddDefaultParameter("If-Modified-Since", DateTime.Now, ParameterType.HttpHeader);
