This is my approach : I reserve last time that a user post a postback to server in a session and in every postback subtract this value from current value. Is there a better way for this?

I am facing a strange issue with my website. If there is a longer inactive period (say a few hours) on my website, and when it is first opened after a longer period of inactivity, it takes almost 50 to 60 seconds to load 1st page. However, thenafter if you reload the indexpage or open any other pages, they are opening in a few seconds. This is trace information about opening my default page . (After 8 ours of innactivity)

View 8 RepliesI would like to record what workstation name or ip address or whatever is getting a session on my web server.
That way I can tell if the user is trying to open the website in a second browser window.
I'm working on a CMS that can run either with or without https enabled on the webserver. I'd like to be able to detect whether https is enabled or not, so that I can act accordingly (for example, display some https-related options to the administrator, and redirect to https for administrator logins).
I'm not looking for Request.IsSecureConnection because that only tells me if the current request is via https. I want something that will tell me whether the current bindings for the site in IIS include a binding for https at the same domain as the current request is on. So, for example, even if the current request is for [URL] and thus not secure, I want to know whether [URL] would work so I can (for example) redirect the user to it if they log in as administrator.
I've had no luck looking for anything in System.Web.Configuration that will tell me about the bindings of the current site, though.
I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch.
I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).
We have a SSO solution with ADFS for logging into our web app, we also have standard setup that uses authentication with our database. I want to setup a solution that allows for both. So now I am trying to figure out, is there any way for ASP.NET to detect if a user is authenticated with Active Directory so I could do this on the fly? If user is logged in through AD, send through ADFS, else, show login screen. I also realize that this may not work if they are setup to use forms based authentication only after the ADFS process is started.
View 1 RepliesI am working on a web project, and here i want to display a label which will display how many user is online and open this site. What can i do
View 1 RepliesI am developing an ASP.NET web application that incorporates google maps. I have an ASP.NET listbox on my page which contains a list of items. When the user selects one of the items, I'd like to show this item on the map. The main complication lies in the fact that google maps uses javascript to control it and the listbox is a server control.
I can think of two ways to do this. The first would involve the listbox calling a javascript function when the user selects a new item. I can then write this function to perform the necessary map operations. Unfortunately, the OnSelectedIndexChanged property of the listbox doesn't seem to support javascript functions.
The second involves wrapping an UpdatePanel around the listbox and getting the listbox to perform a postback. In the SelectedIndexChanged event in VB/C#, I would the need to somehow make a call to a javascript function which would then update the map.
I have a page that uses a user control, I have to detect the pages !IsPostBack in the User Control and do some operation
In the User controls page Load method I tried using the following variations to detect the first load
!Page.IsPostBack
!Page.IsCallback
!this.IsPostBack
!this.IsCallback
!this.Parent.Page.IsPostBack
!this.Parent.Page.IsCallback
None of these worked, they all fail to detect the parent pages 1st load in the usercontrols page load method
I also tried using
if (Request.UrlReferrer.AbsolutePath.ToString() != "/PreviosPage.aspx")
This worked for Fire Fox and Chrome but not IE (IE has issues with Request.UrlReferrer, it throws a null exception)
So I cant use this approach as well.
Two users using the same machine, same browser.
User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!
This is caused by the following mechanism:
Different tabs in the same browser seems to share the same session id. We are storing user auth in cookie and the cookie is shared between tabs (same domain)
Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.
So I'm wondering if there's any other methods to prevent this from happening, other than:
1. Use cookieless session so the session is embedded in uri.
2. Always include a hidden field in page to indicate which user owns the page.

View 3 RepliesIt is a general ASP.NET questions. Many times some items in dropdownlist will become inactive (retired)or active again. It is easy to handle in the new records which use only currently active items. But how to handle the inactive items which need to be used to show history records. It bothered me a long time, not sure how to solve this problem efficiently.
View 7 RepliesI have received an error "Validation of viewstate MAC failed".
I am hosting the web site on my own server, so there is nothing like a "Web Farm or cluster". Can you advise what could be the problem with this error.
I only get this error if the page is left inactive for more then 20 minutes and it throws the exception, so users have log-off and login to continue working fine.
See below full error details.
