Question : Classic ASP Cookie Error

At least some of my website visitors (possibly all) are getting the following error when my script is setting the expiry date of a cookie.

It happens the first time a user calls the page, but if they refresh it works fine.

Microsoft VBScript runtime
Type mismatch: 'Response.Cookies'
/locale.asp, line 24

23: Response.Cookies("locale") = Session("locale")
24: Response.Cookies("locale").Expires = DateAdd("m", 6, Now())

I can reproduce the problem and if I view the cookie information in IE developer tools immediately after the error, that cookie exists and the expiry date is correct, ie. 6 months from today.

Answer : Classic ASP Cookie Error

you are assigning Session("locale") into Response.Cookies("locale")...
seems like for the 1st time Session("locale") does not exist....
during refresh that session gets created and thus does not give any error
