UrlMapping giving 404 Page not found on IIS but working fine on local server port

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 modifi开发者_高级运维cation on IIS Level (if there are any?)

Thanks in advance, Cheers :)

Crack open IIS on the target server.

Go to your Web Application, right-click and select Properties

Select the Virtual Directory tab

Click on the Configuration button under Application settings

In the Wildcard application maps section, add this:

c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll

Make sure you unchecked File exists.

What is likely causing your issue is that in the ASP.NET mapping on IIS, there is a check box "check that file exists" uncheck this and you should be fine.

No real risk in editing this.

Open up the properties on your website, go to the Home Directory tab, and hit Configuration.

Then in there find the .NET mapping, or create a wild card mapping... and make sure the option for 'check file exists' is not checked.

I beleive it happens because IIS6 is unable to hand off requests to ASP.NET when your URLs don't have extensions (like .aspx, for example). In the following sample setup

<add url="~/NewUrl" mappedUrl="~/Default.aspx?UrlId=12345" />

you will get 404 when you try to access http://yousite.name/NewUrl on IIS6. Here's the post in Phil Haack's blog on how to overcome this with wildcard mappings: http://haacked.com/archive/2008/11/26/asp.net-mvc-on-iis-6-walkthrough.aspx

P.S. I know, the post is about ASP.NET MVC, but I think it might help in your scenario too.
