Cookie Creation and Deletion

[dinosf]

Hi guys - I have an issue (mainly that I know so little about javascript) in an asp.net page I am creating. On the page I have several drop down lists that I use the value of the selected value to create a cookie, then on page load I look for that cookie value and depending on what it is I know which drop down list was selected then I parse the string in the sub I call to complete the actions I need. The issue I'm having is getting rid of the cookie and/or setting it's value to nothing. I know I can set the timeout value to a negative value, and I've tried just using repsonse.cookies to change the value. So I'm thinking the problem is one with the path.

I don't know how to modify the cookie creation script to specify the path so when I use response.cookies it's not finding it. If javascript has a default path I might be able to access it with response cookies("../Path/"Values") = ""

or if someone has a better path to reccommend I'm all ears.

I don't need the cookie values after I retrieve them once, so removing it entirely works too. I do have a very specific reason for using cookies instead of regular asp.net session variables.

Here's how I add the value to the drop down list--------
Dim nli As New ListItem
nli.Value = arrR(q, 8)
nli.Text = intMos & " / " & intMiles
Dim strResult As String
strResult = "CreateCookie(this, 'TermCall');this 0].selected=true;"

ddlTerm.Attributes("onChange") = strResult
Me.ddlTerm.Items.Add(nli)

The script to create the cookie is in the html portion of the page -------
<SCRIPT language="JavaScript">

function CreateCookie(myListBox, varType)
{
var txtPlan;

txtPlan = myListBox[myListBox.selectedIndex].value;
document.cookie = "Values"+'='+varType+'|'+txtPlan;
}

</SCRIPT>

I need very specific help, as I seem to have a mental block on it today. Thanks.

When it comes to cookies like this, I normally always use "/" for the path in all cases where it needs to be specified.

Hope this helps,

That's the issue I'm having - I don't know how to modify the script in the html side to add in the path, and if I use that method I need to know where the path leads so I can specify it in the aspx side (e.g. if the page that creates the cookie is located at ./

http://wwwroot/App/Pages/page.aspx

is the cookie designation for the path "/" the same location? when i use response.Cookies("Values") = "" - it does not work it sets a different cookie as nothing, which makes me think the path is different

about the script - I know there is a date item to be added in too - and I'm not sure of the sytax to add in the patch correctly as I don't realy work much with javascript I'm just trying to solve a post back issue with this page.
txtPlan = myListBox[myListBox.selectedIndex].value;
document.cookie = "Values"+'='+varType+'|'+txtPlan
