Looking For Good Method To Handle Data Invalidation Or Timeout?
May 10, 2010
I understand the need for a function like DB_Get_Cached("sql string") that hashes the SQL in order to perform a lookup in memcached for the existence of the data.
function DB_Get_Cached(string SQL)
data = memcache_get_data(md5(SQL))
if (!data)
return DB_Get(SQL)
end if
end function
What is a good method to expand this to handle data invalidation or timeout?
I'm thinking in terms of product pages in an e-commerce site, or user details in their profile.

I'm used to public facing websites that use ASP.net membership - and when the SESSION vbl's timeout we re-direct to the login page like this
Code:
If Session("Yr") Is Nothing Then
Page.Response.Redirect("~Login.aspx?reason=timeout")
End If
And on the login page we check for that reason and put up a label on the screen saying that things timed out to protect sensitive data. This works fine. Now I'm doing a web site that's in house - and when the users connect they get a BROWSER POP-UP to login with the DOMAIN UN/PW - and once they get past that my default page redirects them to a home portal page. What do I do when my session vbl's expire now? I can't redirect to a login page - there is not one. How do I cause the re-authentication to happen more naturally?

I'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.

I need to invalidate cache in a web application when related data is updated in another application (running on the same machine). Both applications use the same database. I know there's SqlCacheDependency. How do is it in terms of performance? Is interprocess communication (e.g. using name pipes) an option in web applications? Does it outperform SqlCacheDependency?

We have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout

Hopefully I am posting this in the correct forum.
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader
Dim param(0) As SqlParameter
Finally [code]...

In our .aspx pages we have user controls each control has a Sql query to fetch data. The caching mechanism to be followed says that fragment cache all the user controls and invalidate the cache based on the respective queries of the user control.How to proceed to add a query dependency to fragment cached user control?

I am trying to create a method that accepts multiple types of controls - in this case Labels and Panels. The conversion does not work because IConvertible doesn't convert these Types.
public void LocationsLink<C>(C control)
{
if (control != null)
{
WebControl ctl = (WebControl)Convert.ChangeType(control, typeof(WebControl));
Literal txt = new Literal();
HyperLink lnk = new HyperLink();
txt.Text = "If you prefer a map to the nearest facility please ";
lnk.Text = "click here";
lnk.NavigateUrl = "/content/Locations.aspx";
ctl.Controls.Add(txt);
ctl.Controls.Add(lnk);
}
}

So, I have a button that populates a datagridview and shows it to the user. What I'd like to do is show a popup from this button just after it's done with the server logic. How can I do that.

I have an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "

The session state timeout is set using this web.config element
<sessionState mode="InProc" cookieless="false" timeout="120" />
The forms auth is configured using this web.config element
<system.web>
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
protection="All"
timeout="30"
name=".ASPXAUTH"
path="/"
requireSSL="false"
slidingExpiration="true"
defaultUrl="default.aspx"
cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
</system.web>
What is the difference between the timeouts specified in each of these elements? If both are different, how would it work?

I'm currently using the fantastic DorkNozzle 'framework' for building a very basic blog in .NET.My first "self-taught" script is as follows, and is for solely retrieving SQL results.
PHP Code:
<%@ Page Language="C#" MasterPageFile="~/Dorknozzle.master" AutoEventWireup="true" Title="Blog" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
<script runat="server">[code]....
I should change to perhaps improve my coding style, without going down the MVC line just yet?

I have a page of each every click has ajax call to my server (hence, the ASP extends the session)
I have ASP.NET session set to Xmin. I want when X+1 min expires, I have expiration page. what I did was to set the JS timer to validate every x+1min to see if the session expired (the problem is that the JS and the ASP session timeouts are not synced)

I know we can write code at the footer to get the sum of rows value.
However it is really a lot of work and all Gridviews I have have different columns etc.
I almost go crazy now if I need to add all these.
Is there a quick way to get this done ? I am so disappointed in .Net4 Gridview this is not enhanced.

I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?
