Dieses Nachschlagen (Umwandlung des IP-Namens in die IP-Adresse) wird durch Domain-Namen-Server (DNS) geleistet. Öffnen einer IP-Socket-Verbindung zu dieser IP-Adresse. Schreiben eines HTTP-Datenstroms über diesen Socket. Rückempfangen eines HTTP-Datenstroms vom Webserver als Antwort.

It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies https://support.google.com/postini/answer/136607?hl=en one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless error 503 otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual 503 service unavailable HTTP status code).

Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body.

Postini Transition: Step-by-stepPostini Transition to Google Postini services have been transitioned to Google, and the Postini Help Center has been retired. For instructions related to Google and Vault, see the Google Help Center and Vault Help Center. About the Postini Transition to GoogleApps The Postini Transition to GoogleApps enables you to copy your orgs, users, and email settings from Postini to the Google Admin console. With this transition, you'll receive email security features that are comparable to your Google Message Security (GMS) features, but through the more robust GoogleApps platform. Google is also taking most of the Google Message Discovery (GMD/Postini archiving) features and rebuilding comparable features into Google Vault. As of June 15, 2015, Google will halt all mailflow through Postini systems. If you do not take immediate action, you may experience mailflow issues on or after that date. See the actions required to prepare for Postini End of Life (EOL). Using this guide The Postini Transition Guide will help you prepare for your service transition, initiate your service transition, and get started with GoogleApps and Google Vault after your service transition is completed. For a complete list of topics and articles in the Transition Guide, see the home page. For step-by-step instructions, click the links below. Before my transition: I haven’t been invited yet. How can I prepare? Configure your firewall If you route mail to an on-premise mail server -- for example, if you have non-Gmail mailboxes or delivery endpoints such as Exchange mailboxes, ticketing systems, or other on-premise systems -- you’ll need to adjust your firewall configuration prior to initiating your service transition. We recommend that you make this change immediately even if you haven’t received your transition invitation. If you do not take these steps now, your mail flow may be interrupted during your transition. For instruct
