I'm creating image (jpg) at run time in my application (ASP.NET/C# 3.0). I need to delete the created image after 30 mins. So is it possible to set expiration to the image after 30 mins when creating the image like setting expiration to cookies.
View 3 RepliesI'm programatically sending an email and I want to set it to expire after a certain amount of time. I tried using the following but it doesn't seem to work:
message.Headers.Add("Expires", Now.AddMinutes(2))
I can see the value in the header but the email doesn't actually expire.
What happens in Asp.Net MVC 2.0, when next request does not come ever to retrieve value from TempData. Is it stored permanently or expires?
View 1 RepliesI am not sure if I am asking this question correctly. Sometimes when you don't know enough, you may not know what to ask. I want to set up memberships with an ASP.NET website. The memberships will have a 14 day free trial period. After that, the user will need to pay a fee if they wish to continue to access the website. I am not sure how to accomplish this. After adding a membership database to the website, setting up roles ect., what do I do next? Do I need to make adjustments to the tables of the database, or write some code somewhere in the application? I have never done this exercise before, Logically, I know that I need to implement something that keeps track of expiration date. Also, how do I prevent a user from just making up new user names and credentialing?
View 4 RepliesI am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here:[URL]
My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired?
1) How/where do I set the lifetime of the session cookie in my web application when using an STS to get claims? From what I can tell, it seems I can only do this programmatically in the erviceConfigurationCreated event.
2) How/where can I make sure that the expiration is sliding?

I don't know if the following is possible or not but in brief, here is what I'm trying to achieve:
1. When a user requests to view a document, they click on a link (could be other) which contains an encrypted query string containing data required to retrieve the relevant document. i.e.[URL]
2. I want to ensure that if after x minutes the user goes back to their history and select the link again or re-type the same url as above that it will not request the document and redirect them to a page letting them know that the requested document "link" is no longer valid.
I don't want to rely on cookies or sessions, so thought that maybe there would be a way to add a datetime token at the end of the existing url but this needs to be done at run-time as the url is already predefined when the link is created, so I'm not sure how can I do this?
ideally, I'd like something like this [URL] where the token would contain the date & time when the link was clicked.
Once re-requested, I would decrypt the token and validate it again the server time and if it was over the x minutes defined, it would redirect me to the "link is no longer valid" page.
I have a scenario in my application that I need to display session expiration time to the user. I set session expiration as 30 minutes in my application, 5 minutes before the session expiration, I need to show message to user that the session is going to expire.
How can I will do this implementation, I am using VS 2010 + MVC 2.0 + JQuery.
I want a specific session variable (in my case Session["level"]) to expire either on the normal 20 min. timer or at 19:30 every day. Because I change a value in my database everyday at 19:30 and I want this session variable to be related to that value. Is this possible?

View 6 RepliesI know that when declaring a page method in ASP.NET, I can specify a CacheDuration like so:
[WebMethod(CacheDuration=60)]
public static void Foo()
{
But from what I understand, CacheDuration only supports absolute expiration. I want to have sliding expiration. So that leads me to believe that I need to access the System.Web.Caching.Cache object somehow. But, since page methods are static, and this is essentially a standalone web service, I'm not sure how to access it statically. The only ways I have seen on Google rely on getting it from the HttpContext. But, there is no HttpContext available to me here, right?Or, do I need to use the System.Runtime.Caching.MemoryCache to do my own caching?
I am using below code to store cookie
if (Request.Cookies["Cookie"] == null) {
HttpCookie CookieFavourite = new HttpCookie("Cookie1");
CookieFavourite.Value = id;
CookieFavourite.Expires.AddYears(1);
Response.Cookies.Add(Cookie1);
} else {
Response.Cookies["CookieFavourite"].Value = Response.Cookies["CookieFavourite"].Value + "," + SomeValue;
}
I specify expiry date equal to 1 year. This cookie value is modified by user almost every day.
But this cookie expire after 12 hrs(approx) although i specity the expiry limit to 1 year.
Using C# and sqlmembershipprovider forms authentication, is there a way to force user password to expire and need to be reset after x number of days?
So if a user launches the website login.aspx page, when they type their userid, it will check if the password is expired and direct them to a Resetpassword.aspx page?
I tried <%= request.cookies("cookiename").expires %> but thats a no go. Tried adding .tostring, no go. what am I to do? Has to be something simple I am missing here.
View 6 RepliesAnything I have tried didn't work. Currenly I have following code to change asp.net session cookie expiration date and path, but asp doesn't want to listen to me. I sends same cookie in Set-Cookie header two times sometimes, sometimes it sends it's default cookie ignoring path and expiration date, sometimes it sends everything as expected, and sometimes it doesn't send Set-Cookie at all. What should I do.
My code in Global.asax
protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
{
/// only apply session cookie persistence to requests requiring session information
if (Context.Handler is IRequiresSessionState || Context.Handler is IReadOnlySessionState)
{
var sessionState = ConfigurationManager.GetSection("system.web/sessionState") as SessionStateSection;
var cookieName = sessionState != null && !string.IsNullOrEmpty(sessionState.CookieName)
? sessionState.CookieName
: "ASP.NET_SessionId";
var timeout = sessionState != null
? sessionState.Timeout
: TimeSpan.FromMinutes(20);
/// Ensure ASP.NET Session Cookies are accessible throughout the subdomains.
if (Request.Cookies[cookieName] != null && Session != null && Session.SessionID != null)
{
Response.Cookies[cookieName].Value = Session.SessionID;
Response.Cookies[cookieName].Path = Request.ApplicationPath;
Response.Cookies[cookieName].Expires = DateTime.Now.Add(timeout);
}
}

I am developing a new website that is membership based with yearly subscriptions. Using VS2010/asp.net4/c#. I have my site up to the point where all my content is ready to go and i can add members to the database to access all the premium content.
However, I have no idea how to impliment a start date and expiration date for that membership. I have been following along with Wrox Beginning asp.net 4.0 from beginning to end and this isn't covered at all. I also have Apress Pro asp.net 4 as well and I cant find anything dealing with that in there either.
What I would love to be able to find is some book or tutorial that i can follow along with and learn from so that this doesn't happen again to me.
In short what I need to do is this.
1. Add new user to defined membership role
2. Apply start/end date to that user
3. When the end date has passed I need to reasign them to a new role and then redirect them to another page with a notification
4. I guess lastly some way to add/manage members as an admin on my deployed site. Durring development i was using the built in Web Site Admin Tool but I just found out that only works on my local machine.
I have a feeling this this will be a very simiple fix but because of my total lack of experience it has been driving me crazy for three days tyring to hunt down info.
I need to remove the data stored in the cache after few minutes (Output and Data Cache).
My concept is binding data from server, storing it in to cache and displayed in the gridview, after a 10 seconds when the button is clicked the cache data should removed and need to show null like nothing. I have build some basic of code, how to get perfectly. I am new to dotnet.
find the below required points and attachments of asp.dot net code and sql query.
1. When page load, gridview should display using Cache.
2. when Clear Cache Button after 10 second from pageload is clicked then the gridview should go hide
3. Reload Cache Button is clicked the gridview again load.
