Redirect - Custom Errors With Mode=remoteOnly And Global.asax Handling Exceptions?

Jul 19, 2010

I have custom errors set in the web config file as follows:

<customErrors mode="RemoteOnly" defaultRedirect="GenericError.aspx" />

Fine and dandy... I like that mode="RemoteOnly" facilitates development...

For unhandled exceptions, I have in global.asax:

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
Response.Redirect("GenericError.aspx")
End Sub

However, unhandled exceptions are going to the generic error page instead of the informative yellow screen of death preferred by developers. I can comment out the redirect in global.asax, but then I need to remember to change it for the production environment. Is there a way I can check in Application_Error whether I am remote or not to determine whether to redirect?

Configuration :: Handling Errors In Global.asax - Application_Error Fires Twice

May 25, 2010

I am handling errors in Global.asax. When I encounter an error in certain pages, the Application_Error event fires twice. On the second trip, Server.GetLastError() returns null. I have a simple page where I throw an error in page load. When that page throws an error the code below works fine. I also have a more complex page with an update panel and many controls. When that page throws an error Application_Error fires twice. I suspect the update panel but update panels are always suspect, right?

There are no try/catch blocks on any of my pages I'm testing with. Custom errors in web.config is commented out. Note that logging and busywork in the Application_Error event are commented out. I'm pretty much just doing a respone.redirect. The problem with the the event firing twice is that the response.redirect fails with an error msg stating that headers have already been sent (adding Context.ClearError and Response.Clear does nothing to fix that).

Should Catch All Exceptions In The Global.asax

Nov 29, 2010

If I am just logging exception details in my web app, do I really need to put in exception handling logic for each tier? Why not just let them all bubble up the stack trace to the global.asax and log them there?

Exceptions - Catch In Page Or Handle In Global.asax (Application_Error)

Jan 27, 2011

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?

Try/Catch In Global.asax While Logging Errors To Db Needed

Nov 3, 2010

So I handle all exceptions in my project within my Global.asax page. For example, on a random page I could have:

[code]....

So my question is in the Application_Error method, do I need the try/catch block when trying to write to the database? I'm thinking I would in case something goes wrong with the connection, etc. - but is this really necessary? Also, what would I do in the catch block if there is an error? At that point I would be catching the error of logging an error which is confusing in its own right.

Difference Between Using Global.asax And Web.config For Error Handling?

Apr 16, 2010

I'm working on a small web application, and I wanted the user to be redirected to a simple error page anytime an exception was encountered. So I wanted to redirect the user to generic Error page "Oooops.aspx" that will log the error in page_load.

I'm thinking that I can use Application_Error in Global.asax, where I can redirect to "Oooops.aspx" so that it displays a friendly error page and it logs the exception (through Server.GetLastError()). I can also use web.config and add "<customErrors mode="On" defaultRedirect="Oooops.aspx"/>" It'll redirect me to a friendly error page and it will also log the exception. What's the difference between these two? Should I use both of them, or just one? And which should I use?

Setting A Session Variable In Global.asax Causes AJAX Errors

Mar 26, 2010

I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour.

If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.

E.g.

I have file called JScript.js containing the code:

function myAlert() {
alert("Hi World");
}

And in my Default.aspx file I reference the js with the code:

<script src="JScript.js" type="text/javascript"></script>

And in the body onload event I call the myAlert() function:

<body onload="myAlert()">

And finally in the Global.asax file:

Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub

If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.

C# - How To Use Global.asax File To Redirect The User

Feb 22, 2011

What should be done if I want to redirect a user based on their ISO Codes?

And how should I detect a website user's IS Code in the first place? Like I know there are these server variables that we use to detect Client IP and all (HTTP_FORWARDED_FOR, REMOTE_ADDRESS, etc) but information about them on the many sites that I have read has got me confused about what to use. Like some say there can be comma separated IPs returned by HTTP_FORWARDED_X and out of those IPs , one is not sure which is the real IP and which are the proxy addresses. Also, that all the IP addresses in returned can be fake.

How to I fetch the REAL IP Address of a person? Like I only want to know what country a particular person is sitting so I can redirect the user accordingly. Secondly lets say a person is sitting in US then I want the user to be redirected to [URL] If a person is visiting my site from Germany, [URL] is the address that I want the person to be redirected to.Also if DE is the ISO Code then I want my GermanMaster.master page to load and if its US then I want that the USMaster.master should load.

So how do I fetch a user's not fake IP address, redirect a user based on that ISO code and then load a master page according to the ISO Code.

How do I go about it? I haven't ever worked with Global.asax before so clueless how to go about it all.

Visual Studio :: Debugging Global.asax Code In Integrated Mode?

Feb 21, 2011

migrating my ASP.NET project from IIS 6 to IIS 7.5 I came across an issue with the Managed Pipeline Mode set to 'Integrated'.I have a Global.asax file in my web root to initialize some objects, gather data etc., however I am not able to hit breakpoints in the associated code-behind file (VS 2008). The code is executing very well (as I can tell from Eventlog), but I want to step into all that initializing there and need to have the debugger attached properly.Everything is working as expected in Classic pipeline mode. Since I'd like to benefit from Integrated Mode features in the future I wonder if I have to give up the ability to debug my Application start and error events...

HttpHandlers / Modules :: Global.asax 301 Redirect Fails On .HTM Files, But Works Fine Elsewhere?

Mar 4, 2011

I just bought an old domain name and am looking to redirect as many old URLs as possible to acquire backlinks intended for the original owner for pagerank reasons. The original site had a lot of static pages ending in .htm which need to be redirected to directories. I use httpcontext in my Global.asax file to initiate 301 redirects and this works great on folder names or .aspx files, but whenever I try to redirect a .htm it fails.

Sample code:

if (HttpContext.Current.Request.Url.ToString().ToLower().Contains("http://www.example.com/oldpage.htm"))
{
HttpContext.Current.Response.Status = "301 Moved Permanently";[code]....

I also tried using my Parallels H-Sphere interface provided by my hosting company to do a IIS redirect, but whenever I hit submit the page just starts an infinate loop of sending a request.

C# - Dictionary Lookup Efficiency & Request Scoped Global Variable Accessible By Global.asax And Pages/etc?

Feb 8, 2011

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.

AJAX :: How To Handle Errors / Exceptions During Postback

Mar 27, 2010

I really want to switch over to ajax, but i can't seem to get my error handlling perfect. If i can't handle errors correctly, I just can't use it. What I really want to happen is to do a full refresh of the Top Frame. How I normally do this is by a similar call to Response.Write(<script>top.location.href = ""</script>). I was currently doing this in Global.asax. This becomes a problem when I error out in an AJAX postback. I've also noticed that There is an AsycPostbackErrorHandler you can attach to the ScriptManager. This is all find an dandy, but it will still hit my Global.asax Application_Error Event.

I am honestly just not sure how to handle this.

As I said, the result I want is....To Reload the Top Frame with some Error Message...whether I have to do some weird redirection or whatever. My problem lies specifically with the Global.asax file.

Handling Exceptions That Happen In A MVC Controller Constructor?

Apr 22, 2010

What's the best way to handle exceptions that happen from within a controller's constructor?

All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.

Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.

If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

Globally Handling Exceptions In Static Aspx [WebMethods]

Mar 16, 2011

The default behavior of a [WebMethod] attributed static method on an aspx page is to return the error to the caller. We are accessing these methods using json, and the only way we have found of capturing exceptions is either a try/catch in every webmethod on the site or using a javascript callback with the error (which has the unacceptable downside of exposing the error to the client).

Is there any way to globally handle these exceptions using the HealthMonitoring setup in ASP.NET?

Web Forms :: Handling Exceptions / Sending Error Message

Nov 24, 2010

I have what is probably a basic question, but I am rather new to writing exception handling code. I thought I understood the concept, but apparently I don't, heres the code:

[Code]....

If I enter in any non-integer values, the textbox is set to nothing and the label displays the error message. However, now that I have verified the textbox contains an integer, I want to continue on and use that value. The remaining code works fine unless there was an exception, in which case the conversion to an int value for x throws an error.

All the examples I have looked at demos the structure of try-catch-finally, but in this instance I am not performing any clean up, I want to execute code when a valid value is entered into the textbox.

This seems top be related to my switch to Visual Studio 2010 Ultimate and .Net 4.0. Since the switch I have seen this problem several times. Is there something new in .Net or VS that I need to do or set to get the exceptions thrown? Other exceptions seem to work fine...it's just with FormView and SQLDataSource that I don't see them.The specific errors I don't see reported include misspelling a field name in the Select, Insert or Update commands in the SqlDataSource.

C# - Application_Error Exceptions Handling, Redirection Infinite Loop And CSS Loading?

Oct 9, 2010

I have error handling in Application_Error event of globals.asax file. Inside this event, I'm using Response.Redirect(~errorview.aspx) method, for redirection to site which is able to handle errors in user friendly way.

Everything works fine, unless exception is rising in Application_Start event. When error occurs there, my application gets trapped in infinite loop with the Application_Error method hit repeatedly. What is more, the page I'm redirecting to never gets hit. Changing Response.Redirect(~errorview.aspx) method to Response.Redirect(~errorview.aspx, false) changes nothing.

The good news is, when Response.Redirect(~errorview.aspx) has been replaced with Server.Transfer(~errorview.aspx), errorview.aspx page succesfully gets hit.

The side effect now is not loading CSS, and errorview.aspx page looks ugly. What is more, the CSS is not loaded only when exception occurs in Application_Start event. Exceptions thrown from any other place don't make the CSS mess.

How I can handle this problem in correct way, and why the CSS is missing in the one particular situation ? What is the appropriate way of handling errors in my case ?

UPDATE

For CSS loading, I'm using this:

<link href="~/Css/Layout/style.css" type="text/css" rel="stylesheet"
runat="server" ID="_uid" />

error page I'm transfering from: http://localhost/APP/Pages/Module/Pages/ErrorView.aspx

css folder path: http://localhost/APP/Pages/Module/CSS/Layout/style.css
