set expiration date cookie problem, it's in past.

I want two write a cookie that expires in 7 days.
But it doesn't function, I couldn't find the cookie. I found out that I had to add 103 days extra to the expire date

with this line Response.Cookies ("GUID2").Expires = DATE + 110 the cookie expires in 7 days.

The behaviour on one virtual win2012 server. I tested the code on other servers and there it works like it should. But every site on this 2012 server I have to add extra days.

This is the code:
asp file
Function CreateGuid()
    CreateGuid = Left(CreateObject("Scriptlet.TypeLib").Guid,38)
End Function

Function CreateGuidCookie(renew)
	If Request.Cookies ("GUID2") = "" or renew = true Then
		Response.Cookies ("GUID2") = CreateGuid
		Response.Cookies ("GUID2").Expires = DATE + 7
	End If
	CreateGuidCookie = request.Cookies ("GUID2")
End Function

Function ExtendGuidCookie
	Response.Cookies .Expires = DATE + 7
End Function

Open in new window file
Response.Cookies["UserSettings"]["Font"] = "Arial";
Response.Cookies["UserSettings"]["Color"] = "Blue";
Response.Cookies["UserSettings"].Expires = DateTime.Now.AddDays(1d);

Open in new window

So I guess I am looking for a setting on the server.. timing of the server is ok.

What is DATE? Looks like a constant.

That is very odd. How about trying to workaround the odd server settings by specifically setting your expire date with DateAdd function (where you can force the date/time unit being added) and then putting that into the cookie.

Like so:

ExpireDate = DateAdd("d",7,DATE)
Response.Cookies("GUID2").Expires = ExpireDate

Open in new window

first, thanks for the response
a response.write "date = " & DATE returns me date today like it should

I tried it but unfortunately .. still had to add 110 (7 + 103)  days the generate a cookie that expires in 7 days.

And what does
response.write "date = " & DateAdd("d",7,Date())

Open in new window

Also test
response.write "date = " & CDate(DateAdd("d",7,Date()))

Open in new window

response.write "date = " & FormatDateTime(DateAdd("d",7,Date()) ,1)

Open in new window


And also test formatting the date value for your cookie using an explicit US format (mm/dd/yyyy).

I'm sorry, took long till I had time again. colleagues on holiday etc.

respectively these response writes returns
date = 03/08/2016
date = 03/08/2016
date = miércoles, 03 de agosto de 2016

hmm, then I'm pretty clueless. cause the code itself seems to be okay.

How did you find out that you needed to add 110? btw, can you us a proxy like Fiddler to intercept the HTTP traffic to see what your ASP application is sending?

Thnx.. Fiddler helped me to find something odd.. what it already is :)

A server where it is working.. raw headers output
