HTTP caching WCF REST/SOAP action using WebInvoke

I have a WCF Web Service (not Web Api) that looks like this:

public interface ILogsService
{
    [OperationContract]
    [WebInvoke(UriTemplate = "/Find")]
    [Description("-Service description-")]
    FindLogsResult FindLogs(LogsFilterRequest request);
}

I would like to know if there's a way (or a better way) to cache the service response by sending HTTP cache headers back to the client.

I've tested and seen that this can be accomplished by using:

HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);
HttpContext.Current.Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));

But I would like a "cleaner" solution if possible.

This service has aspNetCompatibilityEnabled="true" and will always be hosted in IIS.

Solution

  • Just to close this question, the only way I could get this working was via HTTP Context:

    HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);
HttpContext.Current.Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));
