CookieContainer SetCookie error

**lleemon** · May 24th, 2016, 02:58 PM

I have a request function that allows you to pass url and parameters and will return source which typically works but just not getting an error in the HttpWebResponse cookie header.

The error I get is:
System.Net.CookieException: An error occurred when parsing the Cookie header for Uri 'http://www.indeed.com/resumes?q=fabaceous&l=55378&co=US&sort=date&radius=25'. ---> System.Net.CookieException: The 'Path'='/me' part of the cookie is invalid.
at System.Net.Cookie.VerifySetDefaults(CookieVariant variant, Uri uri, Boolean isLocalDomain, String localDomain, Boolean set_default, Boolean isThrow)
at System.Net.CookieContainer.CookieCutter(Uri uri, String headerName, String setCookieHeader, Boolean isThrow)
--- End of inner exception stack trace ---

Here is the part of the code it's failing:

Code:

Try
                If Not m_hwrResponse.Headers("Set-Cookie") Is Nothing Then
                    Dim ccContainer As New CookieContainer()

                    ccContainer = New CookieContainer()
                    ccContainer.SetCookies(m_hwrResponse.ResponseUri, m_hwrResponse.Headers("Set-Cookie"))

                    m_ccCookies.Add(ccContainer.GetCookies(m_hwrResponse.ResponseUri))

                    LogIt(" + [END] Set Response Header cookies ")
                End If
            Catch ex As Exception
                LogIt("See -set cookie header error details in 'Error' log")
                LogItError("-set cookie header error: " & ex.ToString)
                LogIt(" + Response uri: " & m_hwrResponse.ResponseUri.ToString)
                LogIt(" + Response headers (""Set-Cookie""): " & m_hwrResponse.Headers("Set-Cookie").ToString)
            End Try

The weird thing is that if I break this out to it's only process in a button event it works file as shown below:

HTML Code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="zCookie.aspx.vb" Inherits="zCookie" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

        <asp:Literal ID="litOutput" runat="server" />
    <div>
    
    </div>
    </form>
</body>
</html>

Code:

Imports System.Net

Partial Class zCookie
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim sResponseUri As String = "http://www.indeed.com/resumes?q=fabaceous&l=55378&co=US&sort=date&radius=25"

        Dim uriSite As New Uri(sResponseUri)
        litOutput.Text = ""

        Try
            Dim ccContainer As New CookieContainer()
            ccContainer = New CookieContainer()
            ccContainer.SetCookies(uriSite, sResponseUri)
            litOutput.Text = "added cookie"
        Catch ex As Exception
            litOutput.Text = "Error adding cookie: " & ex.ToString
        End Try
    End Sub
End Class

Any thoughts on why it may error or a fix? Thanks in advance.

How about encoding the cookie value first before assigning it to the CookieContainer object?

Csharp Code:

ccContainer.SetCookies(m_hwrResponse.ResponseUri, HttpUtility.UrlEncode(m_hwrResponse.Headers["Set-Cookie"], Encoding.GetEncoding("iso-8859-1")));

The snippet provided is in C#. But the idea is there. You may also replace iso-8859-1 with the appropriate encoding.
