这个问题有点意思，但题主表意不明，确切的说应该分Web端和客户端两种情况。

想来问到这个问题的不应该是开发Web端的，说说客户端的吧：

1、HttpWebRequest.CookieContainer

Cookies通过HttpResponse传给客户端，通过HttpRequest传回服务端，因此你可以
设置Response.Cookies集合的值修改Cookie

Response.Cookies("MyCookie")("Data") = myCookie

通过读取Request.Cookies集合的值得到Cookies的值

myCookie =Request.Cookies("MyCookie")("Data") & "<br>"

2、本人自编的一个函数，放到一个模块里直接调用即可：

Dim myCookie As String
Public Function LoginAnGetCookie(ByRef sUser As String, ByRef sPass As String) As String()
        On Error Resume Next
        REM 登录网站并获得cookie
        Dim url As String = "网站地址"
        Dim postData As String = "sUser=" & sUser & "&sPass=" & sPass '假设传值的是这样的，实际中可用Fiddler抓取。
        Dim wc As System.Net.WebClient = New System.Net.WebClient
        Rem wc.Headers.Add("Cookie", myCookie)  '可讲第一次获得的Cookie赋值给myCookie，然后在此处传值给网站即可
        wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
        wc.Headers.Add("UserAgent", "Mozilla/5.0(iPad; U; CPU iPhone OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B314 Safari/531.21.10)")
        Dim sHtml As String = wc.UploadString(url, "POST", postData)
        Dim arrAllKeys() As String = wc.ResponseHeaders.AllKeys
        Dim sCookies As String = "Set-Cookie"
        For i As Integer = 0 To arrAllKeys.Length - 1
            If arrAllKeys(i).Equals("Set-Cookie") Then sCookies = wc.ResponseHeaders.Get(i)
        Next i
        Return New String() {sHtml, sCookies} '返回二维数组，其中LoginAnGetCookie(0)是网页源代码，LoginAnGetCookie(1)是登录后的Cookie
End Function

通过读取Request.Cookies集合的值得到Cookies的值

Dim aCookie As HttpCookie = Request.Cookies("userInfo")

读取多值Cookie

Dim aCookie As HttpCookie = Request.Cookies("userInfo")
Dim userName As String = aCookie.Values(“userName”)
Dim lastVisit As String = aCookie.Values(“lastVisit”)
