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.
