View 3 Repliesi'm using asp.net 2.0.
there's a way to add an handler to manage the session_end event without using the global.asax?
(i can't modify my httpapplication code so i need to add the handler externally to it)
Looking for best practice focused answers here with explanations.
Should the presentation layer of an ASP.Net app catch and handle exceptions thrown from the business layer, or should these be allowed to bubble out, where they can all be logged and handled uniformly in the Global.ascx's Application_Error handler?

Is there an event that can tap into in Global.asax to execute some SQL in ADO.NET for logging every time a request is made to the application?
View 3 RepliesI have a need to add an application level event (like Application_Start) but not in global.asax. The reason that I can't use global.asax is because this is a web application for which I don't have source code but I want to add some functionality to it. I need to insert an application start code and was wondering it there was anyway to do it. I'm not sure that if I add a class or aspx page to the sie if it will dynamically compile since this is a web application.

I wanted to access this url in Application_start event in global.asax, Can i some how get it?
[I know i can get it via application_beginrequest or other event]
I got this security warning ReviewVisibleEventHandlers(CA2109)for all event handler methods that are present in Global.asax.cs file(Application_Start,Session_Start,Application_BeginRequest,Application_EndRequest,Application_AuthenticateRequest,Application_Error,Session_End,Application_End.
I am trying to fix this warning by marking all event handler methods that are present in Global.asax.cs file as private. Does it result in any side effects in web application execution?
I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.
I have a registration page where I am saving some information. That is running successfully but when I press ctrl +F5 after registration. I get a message by browser to repeat event which is handled earlier. I have done blank all text values and to false viewstate of every control but It is saving 2 times.

I have a hosting account on DailyRazor.com , i use Global.asax in my project to start a schedule process in Application_Start.When i just publish my website, and upload it, the Application_Start does not Fire, but when i upload the Global.asax to my host it gives an Error but the Applicaiton_Start Event fires up, and then i delete the Global.asax file and everything works.just wondering, What am doing wrong ? or why this meaningless thing happens?
View 2 RepliesI have a site with multiple domains pointing to it. I wanted to redirect all requests to main domain so I've created a method called RedirectToRealDomain("domain.com") to check and redirect all requests to my preferred domainAt the moment it lives on Session_Start but I am planing to move it to Application_BeginRequest event. As I understand Session_Start only raised when new session started but Application_BeginRequest raised on all requests. RedirectToRealDomain method doesn't do any DB lookups or anything expensive apart from comparing strings.

I was under the impression till now that Global.asax is used for application level events and it's a common file for all users. Then what does Session_Start event does in this file. If we have to create user session varaibles then Is this the write place to create those? If someone can kindly clear my confusion on this file and it's methods.

I'm using the HttpRunTime.Cache.Add to create a routine that runs every 5 mins to post data out of my app to the main DB, and this works fine. However I also need to import some files from disk in this routine. I have my document directory set up in my web.config as a ~/ relative path and resolve this in normal controller actions using Server.MapPath(string). How can I do this in my Global.asax.cs code -when I try to access it, it throws an error?
View 3 RepliesI have a custom error handler in the global.asax's Application_Error method, when an error occurs I use the following code to transfer user to the error page:Server.Transfer("/Error/");
However without specifying the actual page name the code above breaks with "Error executing child request for /Error/" exception.So if I use Server.Transfer("/Error/Default.aspx") it works fine with no problems.Also using Response.Redirect("/Error/") works fine too, however we want to keep using Server.Transfer to retain URL displayed in the address bar when the error page is displayed so users can simply refresh the page to retry accessing the original offending URL.Would be grateful if anyone can comment on how to get the Server.Transfer method working without specifying the actual aspx page name.
I've got an website running on a third-party hosting server. Now I've got a few objects in global asax. But once in like 6 hours or so (didn't really check how long) the object gets reset to default values.Is this an problem in global asax that it reset's himself or is this the server on which I'm hosting?
