public:
property int MaximumAutomaticRedirections { int get(); void set(int value); };
public int MaximumAutomaticRedirections { get; set; }
member this.MaximumAutomaticRedirections : int with get, set
Public Property MaximumAutomaticRedirections As Integer
Eigenschaftswert
Die maximale Anzahl von Umleitungsantworten, denen die Anforderung folgt. Der Standardwert ist 50.
Ausnahmen
Der Wert wird auf 0 oder weniger festgelegt.
Beispiele
Im folgenden Codebeispiel wird der Wert dieser Eigenschaft festgelegt.
#using <System.dll>
using namespace System;
using namespace System::Net;
using namespace System::Text;
using namespace System::IO;
// Specify the URL to receive the request.
int main()
{

HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create(args[1]));
// Set some reasonable limits on resources used by this request
request->MaximumAutomaticRedirections = 4;
request->MaximumResponseHeadersLength = 4;
// Set credentials to use for this request.
request->Credentials = CredentialCache::DefaultCredentials;
HttpWebResponse^ response = dynamic_cast<HttpWebResponse^>(request->GetResponse());
Console::WriteLine("Content length is {0}", response->ContentLength);
Console::WriteLine("Content type is {0}", response->ContentType);
// Get the stream associated with the response.
Stream^ receiveStream = response->GetResponseStream();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader^ readStream = gcnew StreamReader(receiveStream, Encoding::UTF8);
Console::WriteLine("Response stream received.");
Console::WriteLine(readStream->ReadToEnd());
response->Close();
readStream->Close();
}
