determine cookie expiration

I have a winforms app that access a web resource using forms authentication.
I programatically login to the site, and catch the cookies. I then pass the
cookies to my httpwebrequest.

I neet to know how to tell when the cookie has expired so that I can have
the app login again.

The other issue is session timeout. the web resource is Exchange Outlook Web
Access. It will time an inactive session out. how do I determine if my
session has timed out, so I can fource another login

I have considered logging in for every httpwebrequest, but when attempt to
do that I get a timeout response from the login procedure unless I unload
the app and start it back up again. At first I thought I was not disposing
the httpwebrequest or the cookie cache properly, but I double checked and
made sure that all my objects were disposed, or set to equal nothing when
the procedures finishes

I link to a web site from an Excel spreadsheet. The page i link to is getCookie.asp which sets a cookie then returns back some html which opens a new window, to the same site but a different page (same folder). The cookie is not received. Can someone explain why? I worked around this by adding a cache-control header with a value of no-cache. This fixes the problem. Unfortunately that causes another problem with Internet Explorer...

Hi, we've the following problem : We have an asp-application which sets the cookie on first login. The cookie will never be touched during user access. The user can work the whole day, but after 6 to 7 hours, the cookie get 2-4 new asp-sessionid's thus overwriting the very first entries in the cookie. Does anyone had the same problem or has a solution. The server is a w2003 enterprise the client has windows xp sp2.

Hi, (newbie question) I've created some simple .NET ASP application that should store cookies at the client machine. According to the documentation cookie expiration time is set via HttpCookie.Expires property, but property value is the time of day on the client. How can I possibly know client local time ?

Hi, In my website, i have a cookie that allows the user to remain logged in for upto 90days. So I'm setting the cookie expiration time to 90 days in the future from the time the user logs in. I've been testing my code and for some reason, the cookie expires randomly before even 24 hrs has passed. Yesterday it expired after 11hrs and 20mins. Any idea why my cookie expiration isn't working?
