I've just inherited a website (ASP.Net 2.0) written by someone else that I need to maintain. The code is not horrible, but it has a number of things that make the website run incredibly slow. I have an idea to monitor this, and I want to see what more experienced developers think of it. My objective right now is to find out when pages ...
I need a method to run every so often that does some database processing. However, I may need it to be triggerable by an admin on the site. But I don't want this method being run more than once at the same time, as this could cause issues with the way it hits the database. For example, could I... Create a singleton class that runs th...
Hello, A couple of questions regarding the role of global.asax: Why is it not included in the Website Project in Visual Studio? Are there other ways of achieving the same functionality without this file? If I would create a Web Application project, as far as I remember, a global.asax file would be created. If I were to delete it, would...
I'm trying to debug something in the global.asax.cs file in an ASP.NET web app and have set a breakpoint in the Application_Start() event however that event is not getting fired when I start the web app inside VS2008. I'm targeting the 3.5 framework. What could prevent this event from being fired? Or how could I have messed up the proje...
I am wondering under what circumstances I should be putting application initialisation code in Application_Start() vs Init() in my Global.asax file? The distinction between the two doesn't seem very obvious to me, other than Application_start gets called first, then Init(). Why would I use one over the other? Does it really make a di...

Hi folks, i want to check if the Session contains some key/value data, in my global.asax. I'm not sure when the earliest possible time (and method name) is, to check this. thanks :) ...
Consider a web application that resizes large tiff files on the fly. Each large tiff file is resized into a jpg thumbnail and larger jpg when the user invokes the operation. The dimensions of these converted files is always the same. During a code review yesterday, one of the other developers asked me why I set those dimensions in my gl...
One of our applications has a mechanism for emailing our Helpdesk automatically should it encounter a certain level of exception. One particular exception, a NullReferenceException, is causing a few problem and I believe it is caused by IIS recycling and losing the session. To prove this I want to log when the application is started/sto...

Hi! I need to replace some data that's sent from every page on my site, and I think doing it with Global.asax.

Hi, My goal is to write a cookie when the user authenticates. We are using a crappy framework that hides its source code and event model so when I use their login control I can't set a session timeout on it! Anyhow, I am trying to write a cookie when the user is logged in, and then refresh the cookie expire time on subsequent page vie...
I am using Global.asax to perform logging at the end of each request via the Application_EndRequest event. However, I am seeing some odd behavior of certain values stored in the HTTPContext.Current.Items collection. Below is the debug output for a nullable Enum. You can see that there is a value, but HasValue resolved to False?! {Syst...

After deployment on IIS 6 methods declared in Global.asax (for Application Start, etc.) are not executed. The same code on IIS 5 works properly. What can be the reason? Is it the problem with permissions/configuration? ...

I have two questions: 1) I have a few global variables for my website declared in my global.asax file. They are simple, small key/value pairs and there are only a few of them. Is this a good practice for values that are small and need to be accessed by almost every page on my website? Storing them in the database and requiring a db look...
I need to use Server.MapPath() to combine some files path that I store in the web.config. However, since Server.MapPath() relies on the current HttpContext (I think), I am unable to do this. When trying to use the method, even though its "available", I get the following exception: "Server operation is not available in this context." ...
