Custom Errors Not Working / 404 Page Not Found - How To Fix It
Mar 16, 2010
I'm trying to set up custom errors for asp.net in webconfig/global.asax on Server 2003, IIS 6. Got it working find for .aspx pages but not for any htm or html pages. So I found the article describing how to open IIS manager, click configuration, copy path for .aspx extension and add one for .htm Did that.
Restarted website: Now I get the blank white page explaining there's a problem but not the 404 page not found
For some reason the Custom Errors for 404 pages are not working on my production server, but they work fine on development. Instead of going to the custom 404.aspx page, it goes to the ugly IIS 404 page.
Here is my Custom Errors protion of my web.config:
[Code]....
I changed the defaultRedirect to also go to my 404.aspx page just to make sure I was catching everything, but still it does't work. I know I could change the IIS 404 error to also point to my 404.aspx page, but that will not work for me because I need to capture the "aspxerrorpath" in the querystring for .net 404 errors. The IIS method will not give me that.
I am just hoping it is a server configuration I missed somewhere, but everything on production looks the same as on development.
Here's my Application_OnError event sink in global.asax.vb:
Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Dim fourOhThree As Integer = DirectCast(HttpStatusCode.Forbidden, Integer) Throw New HttpException(fourOhThree, innerMostException.Message, innerMostException) End If End Sub
You'll see that if we've got an innermost Exception of type AccessDeniedException we throw a new HTTPExcpetion with a status code of 403 AKA 'forbidden'
So what we're expecting is a redirect to the AccessDenied.aspx page. What we get is a redirect to the ServerError.aspx page.
We've also tried this:
Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Context.Response.StatusCode = DirectCast(HttpStatusCode.Forbidden, Integer) End If End Sub
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored
[code]....
This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.
I am a more than a little confussled, my build succeeds with no errors but when I run without debugging only my error page shows up? I tried switching the custom errors to "Off" but it still shows up the error page.
These are some extracts from my web.config file on development server. Intelligencia URL was fine but when deployed on production(IIS 5 on both servers) it returns page not found(404 error) on every rewritten url except for one which has ~/(guid value).aspx/value (rewriiten url) working
Well I am having a problem when I have put my .NET 2.0 web site on IIS 6. I have used UrlMapping to redirect some old urls. It is working fine when I am using it on the VS local server port but when I deploy it to IIS 6, its giving a 404 Page not found error.
I've found that in a few forums they are talking about using Wildcard Mapping, but none of them provide me with a good explanation of how to achieve this. Added to this, what are the security risks of doing such a modification on IIS Level (if there are any?)
A 'High Res' snap shot of the 'Error List' is available at http://cforedu.com/snap_2.pdf Question, how do we debug and remove the syntax errors found in the .net button codes (Default.aspx.vb)?
To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
I got this error at time of running ma published website but only for 1page this error occurred how it can be solved.
I've searched a fair bit round and tried a number of potential solutions, suggested on their respective threads on various sites, to which none have worked for me.
My objective is to make sure the date entered, and to be stored, is not 'less than' (before) the present datei.e. Booking a reservation for a restaurant.
The first is:
"The ControlToValidate property of 'cvDate' cannot be blank..."
I've tried specifying it in page_load and .aspx source, the same has happened in both, in addition to ValueToCompare. I cant understand why it cant detect it?
I have a problem, its completely i dont why this happening.say i have site its workign most of places.but when i'm check some place its going to custom error pagei'm using url rewriting handler, is it may be?
I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder. Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.
this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)
If I were to specify a page for redirect using the ASP.NET Custom Errors feature, would my application still spit out the HTTP status code for that particular error?
For example if had a line in my web.config that had all Internal Server Errors redirect to Errors/500.aspx and then I encountered a 500 error, I would then be redirected to my custom Errors/500.aspx page. Will my application still respond with a HTTP 500 at any point in this exchange?
I have the following code but when i try and create a new IQuerable i get an error that the interface cannot be implemented, if i take away the new i get a not implemented exception, have had to jump back and work on some old ASP classic sites for past month and for the life of me i can not wake my brain up into C# mode. The code is to create a list of priceItems, but instead of a categoryID (int) i am going to be showing the name as string.
public ActionResult ViewPriceItems(int? page) { var crm = 0; page = GetPage(page); // try and create items2 IQueryable<ViewPriceItemsModel> items2 = new IQueryable<ViewPriceItemsModel>(); // the data to be paged,but unmodified var olditems = PriceItem.All().OrderBy(x => x.PriceItemID); foreach (var item in olditems) { // set category as the name not the ID for easier reading items2.Concat(new [] {new ViewPriceItemsModel {ID = item.PriceItemID, Name = item.PriceItem_Name, Category = PriceCategory.SingleOrDefault( x => x.PriceCategoryID == item.PriceItem_PriceCategory_ID).PriceCategory_Name, Display = item.PriceItems_DisplayMethod}}); } crm = olditems.Count() / MaxResultsPerPage; ViewData["numtpages"] = crm; ViewData["curtpage"] = page + 1; // return a paged result set return View(new PagedList<ViewPriceItemsModel>(items2, page ?? 0, MaxResultsPerPage)); }
I need to get the free Google charts working over SSL without any security errors. I am using c# and asp.net.As Google charts does not support SSL by default, I am looking for a robust method of using there charts but ensuring my user doesn't get any security warnings over their browser.ne thought was to use a handler to call the charts api and then generate the output my site needs.Similar to Pants are optional blog post. I haven't been able to get this example working at this stage.
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?
The following references to user controls give the error "Row not found or changed." However, when I remove any one of the references, the results are perfect and everything displays fine.
