下面是我认为导致错误的代码部分

 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        If Page.IsValid Then
            SqlDataSource1.Insert()
            Dim x As String
            x = "http://www.cc.com/bookingrequest/confirm.aspx?date=" & HttpUtility.UrlEncode(now.Text) & "&tfname=" & HttpUtility.UrlEncode(lofname1.Text) & "&tlname=" & HttpUtility.UrlEncode(lolname1.Text) & "&comp=" & HttpUtility.UrlEncode(Request.QueryString("comp")) & "&land=" & HttpUtility.UrlEncode(land.Text)
            Dim mail As New MailMessage()
            mail.To = locemail.Text
            mail.From = "info@cc.com"
            mail.Subject = "Booking Request for " + locfname.Text + " " + loclname.Text
            Dim url As String

            mail.Body = HttpContent(url) + Environment.NewLine + "If You Can't See This E-mail, Please Click The Link.  " + x
            mail.BodyFormat = MailFormat.Html
            mail.UrlContentBase = url
            SmtpMail.SmtpServer = "mail.cc.com"
            SmtpMail.Send(mail)



            Dim mail1 As New MailMessage()
            mail1.To = "info@CC.com"
            mail.Cc = "JS@cc.com"
            mail1.From = "BookingRequest@cc.com"
            mail1.Subject = "Booking Request for " + locfname.Text + " " + loclname.Text + " made by " & Request.QueryString("comp")
            mail1.Body = HttpContent(url) + Environment.NewLine + "If You Can't See This E-mail, Please Click The Link.  " + x
            mail1.BodyFormat = MailFormat.Html
            mail1.UrlContentBase = url
            SmtpMail.SmtpServer = "mail.cc.com"
            SmtpMail.Send(mail1)

            Response.Redirect("http://www.cc.com/bookingrequest/confirm.aspx?date=" + now.Text + "&tfname=" + lofname1.Text + "&tlname=" + lolname1.Text + "&comp=" + Request.QueryString("comp") & "&land=" & HttpUtility.UrlEncode(land.Text))

        End If

    End Sub

    Private Function HttpContent(ByVal url As String) As String
        Dim objRequest As Net.HttpWebRequest = System.Net.HttpWebRequest.Create(url)
        Dim sr As New IO.StreamReader(objRequest.GetResponse().GetResponseStream())
        Dim result As String = sr.ReadToEnd()
        sr.Close()
        Return result
    End Function

因为远程服务器由于某种原因未接受您的请求。我会尝试手动打入你的代码生成的一些网址，看看他们是否给你任何想法。或者联系负责cc.com的服装，了解如何正确提交远程请求。

通过猜想，假设它是.ASPX，它可能期望您的Web客户端处理会话cookie，并且当您没有它时它可能会崩溃。但是从这里可以肯定地说不出来。

为什么我在此代码中出现500错误
