System.Net.Http.HttpClient Disable Caching (.Net Standart Project)

In my .NET Standard project I'm using System.Net.Http.HttpClient. How can I disable all caching (request caching especially) in HttpClient?

If server sends responses with no cache header problem solves. But I want to make this on client side. I want to completely disable all caching.

Thanks.

Edit: It looks like I could use WebRequestHandler but this does not exist in .NET standard. I can only use HttpClientHandler but HttpClientHandler doesn't have any option about caching.

Solution

  • You can use CacheControlHeaderValue in HttpClient

    using System.Net.Http.Headers;

httpClient.DefaultRequestHeaders.CacheControl = new CacheControlHeaderValue
{
  NoCache = true
}
