Infinite loop when using cookieless session ID on Azure

2441 ワード

If you use cookieless session ID and deploy them on Azure, you might get infinite loop when you query your web site, and browser would down. In this scenario, you need to overwrite ASP.NET default ISessionIDManager.
In method GetSessionID, your could should be below
public string GetSessionID(HttpContext context)

{

    var id = HttpContext.Current.Items["AspCookielessSession"] as string;

    // Azure web site does not support header "AspFilterSessionId", so we cannot get context.Items["AspCookielessSession"]

    // for azure web site use, Headers["X-Original-URL"] format: /(S(xxx))/default.aspx

    var originalUrl = HttpContext.Current.Request.Headers["X-Original-URL"];

    if (!string.IsNullOrEmpty(originalUrl))

    {

        var match = Regex.Match(HttpContext.Current.Request.Headers["X-Original-URL"], @"/\(S\((\w+)\)\)");

        if (match.Success)

        {

            id = match.Groups[1].Value;

        }

    }



    return id;

}

Don't forget to change your web.config file.
