Cookie Collection 1

[developer155]

Hi I have a function that sets a cookie after a user action.
Basically what happens is a use views properties. I set a cookie whe a property is viewd (tracknum and propnum are property numbers). As you see, when user looks at next properrty, cookie will be overwritten with next property's numbers. I need to keep up to 10 property cookies. How can I do this? I will also need to go throught all the property cookies and check if a certain one exists. Here is what I have for setting a single cookie:
public void SetLeadCookie()
{
HttpCookie cookLead = new HttpCookie("lead");
cookLead["tracknum"] = myQsp.GetValByKey("tracknum");
cookLead["propnum"] = myQsp.GetValByKey("propnum");
Response.Cookies.Add(cookLead);

}

thanks for any help!

You could either change the name of the cookie so that each property has it's own individual cookie (then you simply have to check for the existence of each cookie). Alternatively, you can use the same cookie and change the key names that you use and maybe append the property number onto the end of each one. That way, you'll have to read the cookie and check for the existence of the relevant property number.

Thanks,
but how do I go through values or keys for a cookie:

foreach ( ??? val in cookLead.Values)

Also, how many keys can one cookie have

 

[ca8msm]

Just loop through the Values e.g.

        For Each s As String In ck.Values
            Response.Write(s)
        Next

Oh, and I'm not sure how many keys/values a cookie can have but I think they are limited to around 4k.
