Demonstrates the DigestAuth property to do HTTP Digest Authentication. C

#include <C_CkHttp.h>

    const char *jsonResponse;

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  To use HTTP Digest Authentication:
    CkHttp_putLogin(http,"myLogin");
    CkHttp_putPassword(http,"myPassword");
    CkHttp_putDigestAuth(http,TRUE);

    //  If you would like to see the HTTP session log to see how 
    //  HTTP digest authentication worked.
    CkHttp_putSessionLogFilename(http,"c:/temp/qa_output/sessionLog.txt");

    //  Run the test using this URL with the credentials above.  
    //  (Works while httpbin.org keeps the test endpoint available.)
    jsonResponse = CkHttp_quickGetStr(http,"https://httpbin.org/digest-auth/auth/myLogin/myPassword");

    //  Output:
