HTTP Status Code 501, 502, 505, 520 RRS feed

  • Question

  • Hi,

    I have an application that uses ActiveSync to synchronize folder content. I would like to ask what the expected behaviors when the client receives the following HTTP statuses when sending a SYNC command request to server:

    • 501
    • 502
    • 505
    • 520

    The document only covers limited number of HTTP error statuses and does not mention what the client is supposed to do.

    I would greatly appreciate any help.

  • Hi sleung496, 

    As I mentioned in your other post, this is also something that would defer to RFC2616. Most of the status codes you list here would probably require follow-up with the implementation owners as they indicate the server side code is not designed to handle the request. There are no Exchange specific behaviors that the client needs to act upon.

    I hope this answers your question.
