How To Get The IP Address Of The Current Website In Global.asax
Nov 16, 2010I'd like to do this in the Application_Start method, so I can write a 'robots.txt' file if the site is running on a test server.

Why HttpContext.Current.Session Is Null In Global.asax
Nov 15, 2010I'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request. I'm using the 'Application_AuthenticateRequest' and the 'Session_Start' methods.
First round:
AuthenticateRequest called. The following code ran:
[Code]....
The _current variable is a private static field published through a static property. In the first round the Session is null, and I think it's ok because the Session_Start not called yet. The Session_Start looks like this:
protected void Session_Start(object sender, EventArgs e)
{
Session["EMPLOYEE_DATA"] = EmployeeFactory.Current;
}
In the next round the Session_Start is not called of course but in the AuthenticateRequest I can't access to the session. The HttpContext.Current.Session is null and the this.Session reference throw a HttpException says the "Session state is not available in this context".
However I can access the Session from any of the page_load events but it's a bad practice I think that I put authentication every page_load.
Configuration :: Global.asax Ignored In Compiled Website?
Jun 2, 2010I have a website with a global.asax file with some debug code in Application_Start, which inserts some debug information in a table in the db:
void Application_Start(object sender, EventArgs e)
{
Log.LogToDb("App Starts");
}
I have 2 versions of the same website, one compiled and the other one just plain code.The plain code website correctly inserts these records in the db, but the compiled one is not doing it.
I have a feeling the Global.asax file is being ignored by the compiled website. I can see the dll for it in the in folder: App_global.asax.compiled and App_global.asax.dll although I can't see a Global.asax file in the root folder (do I need one?)
I must say the website is compiled with MSBuild and then obfuscated using Dotfuscator.
Configuration :: Global.asax Events Not Fired In Website
Mar 11, 2010I have recently published my website, it worked fine but the only issue is that the error handling code in the global.asax never works. It works when I tested the website on my localhost but not when it is deployed onto my hosting provider.
I tried moving my global.asax file onto my root directory (not the bin) on the hosting folder, then my whole website wouldn't even start. I get the error message "System.Web.HttpException: This server variable cannot be modified during request execution."
But if I remove the global.asax, then it is running fine again.
Note: I didn't use the publish function in Visual Studio to publish my website, I sent the files over one by one via cPanel. Note: I googled about this, a lot of them are saying about global.asax being precompiled into a dll, but I can't find that dll in my local computer.

View 18 RepliesConfiguration :: Why Global.asax Error Is Occurring When Internal IP Check And Net App Managers Pings Website
Apr 23, 2010When I run my app locally I get no errors. No error from Global.asax, no redirection to an error page. Everythings works fine.
When I deploy my app to a test server, my app run there with no errors. No error from Global.asax, no redirection to an error page. Everythings works fine on the test server.
But when I deploy my app to production server, the app runs fine but I keep getting errors (emailed to me) from Global.asax. On production server we have these security apps that run and keep hitting all URLs of the app on the server. Just to make sure they are working fine. When these security app hit URL of my app, my application runs fine but it gives out this global.asax error. The funny thing is that error is empty. The error are emailed to me and the email is empty. Nothing there.
There are several other apps running on the same server. My app has its own app pool and is configured correctly.
C# - Dictionary Lookup Efficiency & Request Scoped Global Variable Accessible By Global.asax And Pages/etc?
Feb 8, 2011I 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.

View 2 RepliesC# - Global.asax Application_BeginRequest
Nov 4, 2010I 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.

View 3 RepliesC# - Server.Transfer In Global.asax?
Dec 29, 2010I 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.
