Cookies will disappear?

[bungpeng]

My application use cookies when user login.
All my page load will check if cookies not exist then redirect back to login page.

The problem is, even user not logoff, the cookies will suddenly disappear and redirect user to login page. is it possible?

 

[FZelle]

sure, how do you create the cookie?

 

[bungpeng]

This way:

Dim objID As New HttpCookie(clsCookies.UserID, sID)
objID.Expires = DateTime.MaxValue
Response.AppendCookie(objID)

Even I not set the "Expires", the same problem still occurs...
So I don't think cookies disappear because of expires...

 

[bungpeng]

No body face the same problem as me?

What happens if you set the .Expires to a more reasonable value i.e. a year or two rather than .MaxValue?

 

[bungpeng]

Test already, still the same problem...

What browser(s) are you using? Is the browser configured to block cookies?
What is the URL of the page that iniitially generates the cookie compared to the ones that attempt to read it?

 

[bungpeng]

IE, did not block cookies, because in other page is ok.
In the same domain... the main point is, sometimes can, sometimes cannot, even I use F5 key to confirm it is not cache by browser...

Will server setting affect cookies?

 

[bungpeng]

May I know whether server configuration or web.config file affect it?
