you can use a proxy page. Here you can set your period of time ect.I have attached an example of proxy modified for call dynamic token in proxy pageIn method gettokens you can change your rules
public string GetToken(string uri)
{
foreach (ServerUrl su in serverUrls)
{
if (su.MatchAll && uri.StartsWith(su.Url, StringComparison.InvariantCultureIgnoreCase) && su.DynamicToken)
{
// Code to dynamically get the token
string tokenService = string.Format("https://{0}/arcgis/tokens?request=getToken&username={1}&password={2}&expiration=30", su.Host, su.UserName, su.Password);
string token;
// This script is added to force the application to certify the SSL script (if for example you have a self certificate on server)
System.Net.ServicePointManager.ServerCertificateValidationCallback += delegate(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
return true;
};
System.Net.WebRequest tokenRequest = System.Net.WebRequest.Create(tokenService);
System.Net.WebResponse tokenResponse = tokenRequest.GetResponse();
System.IO.Stream responseStream = tokenResponse.GetResponseStream();
System.IO.StreamReader readStream = new System.IO.StreamReader(responseStream);
token = readStream.ReadToEnd();
return token;
}
else if (su.MatchAll && uri.StartsWith(su.Url, StringComparison.InvariantCultureIgnoreCase))
{
return su.Token;
}
else
{
if (String.Compare(uri, su.Url, StringComparison.InvariantCultureIgnoreCase) == 0)
return su.Token;
}
}
if (mustMatch)
throw new InvalidOperationException();
return string.Empty;
}
