I have a page with URL mysite.com/mypage.aspx and I want visitors to be redirected to this page if they go to mysite.com/mypage. It is only for this page and I wonder if this is possible to achieve in web.config. I do not have access to any source code, only to web.config (via FTP). I tried to log in to our web hosts control panel to check if there's any settings there I can use but it seems to be down for the moment.
So can I do something like this in web.config (it's ASP.NET 2.0 if that matters)?
Thanks in advance.
Edit: I tried
<urlMappings enabled="true">
<add url="~/index.htm" mappedUrl="~/default.aspx"/>
<add url="~/mypage" mappedUrl="~/mypage.aspx"/>
</urlMappings>
It works for index.htm but not (obviously) when there's no extension in the first place.
To the best of my knowledge, you can't do any url routing in code with asp.net 2.0 (only 3.5, 4.0 and you need source code for those).
Do you have access to IIS to UrlRewrite

Is it possible to re-direct a request for a page 'XYZ.aspx' to 'ABC.aspx', without writing any code? We are using ASP.Net 4.0 with IIS 7.5.
The idea is that we want to remove XYZ.aspx page from our website, and if users still use old bookmarks that point to XYZ.aspx, then we want them to be taken to ABC.aspx in an automated manner.
there seems to be a few ways, link should hopefully help you out.
http://www.trainsignal.com/blog/iis7-redirect-windows-server-2008
you can forward the user through web.config file or you can do it through IIS too. but I I were you I would use web.config. in shared hosting u cannot touch IIS.
I found the answer. One needs to use the following in web config, and that's it.
<location path="XYZ.aspx">
<system.webServer>
<httpRedirect enabled="true" destination="http://localhost/mysite/ABC.aspx" httpResponseStatus="Permanent" />
</system.webServer>
UPDATE : This will also work if any query string parameters are passed to the page XYZ.aspx.
I have a comment form on my website on contact.aspx. I want to be able to put up a redirect from /comment (no extension) to point to contact.aspx.
I set up the following url mapping in my web.config and when I test locally it works fine. When I post it to production, the redirect doesn't happen and I get the IIS 404 error.
<system.web>
<urlMappings enabled="true">
<add
url="~/comment"
mappedUrl="~/contact.aspx"/>
</urlMappings>
I'm assuming this is because IIS isn't serving up the request to the asp.net engine and I'm using a shared hosting environment (discountasp.net) so I don't have direct control over IIS to configure it there. I can always put in the subfolder and a default.aspx that will redirect for me, but I thought I would inquire about this route first.
What does the collective think?
Ask your web host if they can configure your virtual directory to serve all requests through ASP.Net.
Many hosts (mine included) are willing to do this. (Mention ASP.Net MVC, which requires this)
I have a customer of ours that sent out a publication referring to my site but they used the wrong address...they did not provide a page name...it looks like this:
mywebsite.org/Resources/toolkits/bridging
when it should have been
mywebsite.org/Resources/toolkits/bridging/default.aspx
Is there a way to tell ASP.NET to default to this default.aspx when it sees this kind of request or even better, have IIS 7 handle this easily?
This site is live so I would like to avoid having to introduce code if possible.
As per other suggestions, this should be done in the IIS configuration for your website using the IIS Admin tool.
There is however, another alternative - you can add a section in the web.config of your actual ASP.NET application, allowing you to override the IIS configuration right from your application:
<system.webServer>
<defaultDocument>
<files>
<clear />
<!-- Specify each of your files by order of preference here -->
<add value="Default.aspx" />
<add value="Index.aspx" />
<add value="MyOtherPage.aspx" />
</files>
</defaultDocument>
</system.webServer>
The caveat to this though is it may be a little obtuse when the IIS administrator can't figure out why the server configuration isn't working the way he's got it configured. It's not always right to do something just because you can.
Finally, just in case you don't have access to the IIS server or your IIS administrator has reasons for not adding Default.aspx to the default document list in the IIS configuration and for whatever reason, you don't wish to override the IIS configuration in your web.config file, then the quickest and simplest way is to simply create a file called default.asp in that directory containing:
<% Response.Redirect("default.aspx") %>
Default.asp is in the default document list on IIS. The code will automatically redirect the call to the correct page. The downside to this approach though is that there's a performance hit - every time someone calls default.asp - directly or otherwise, the redirect needs to happen which isn't free.
In the Documents tab of the web site properties in IIS you can specify default documents. If you are using .Net2.0 or later on that machine then Default.aspx should already be set....
Default.aspx is not, oddly enough, set as the default document in an IIS installation; In IIS 7, the setting is under "HTTP Features", called "Default Document". Add default.aspx to that list and you should be OK.
If not, you'll need to add a 404 handler that redirects when it sees that URL.
We are using the Intelligencia URLRewriting module for asp.net with version 2.0 of the framework and IIS6. Our URLs typically have no extension.
I understand that IIS6 cannot really deal with this situation without a blanket wildcard (which causes other problems).
However, it works! Sometimes. At other times (e.g. on one dev's machine, and on my machine when I point a different virtual directory at the app) it doesn't. By "it doesn't work" I mean the configured HttpModules never even get hit.
Can anyone explain this?
Thanks.
So it turns out what was happening was the following:
request comes in to (say) http://website/products/productid
IIS can't find this hence we get a 404
by chance we have a custom error page set up in IIS for 404s
this error page sticks the referring URL on the end of the 404 error.aspx page
so we get a redirect coming into asp.net along the lines of:
http://website/error.aspx?404;http://website/products/productid
our URLRewriting regexes were now set up in such a way that they discarded the error.aspx bit and dealt with http://website/products/productid as if it were the actual URL
so asp.net renders http://website/product.aspx?id=productid as requested!
I guess this could prove to be a useful kludge for someone, but we're moving to an isapi filter. One heads-up is that this will by default lead to a tight loop of redirects!
If you run a site using the Visual Studio development web server all requests will be handled by asp.net so your HttpModule will run.
On IIS6 this should not happen unless it is set up to forward the requests to asp.net.
Are you sure that when "it works" you aren't running under the Cassini development web server included in VS.NET ? Because extensionless wildcards do work under Cassini, which can be very confusing to say the least.
If you are using an IIS6 with ASP.net 4.0, you must specify and register the modules like this:
<system.web>
<httpModules>
<add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule, Intelligencia.UrlRewriter"/>
not
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule, Intelligencia.UrlRewriter"/>
</modules>
I've set up wildcard mapping on IIS 6, by adding "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll", and ensured "Verify that file exists" is not checked :
on the "websites" directory in IIS
on the website
However, after a iisreset, when I go to http://myserver/something.gif, I still get IIS 404 error, not asp.net one.
Is there something I missed ?
Precisions:
this is not for using ASP.NET MVC
i'd rather not use iis 404 custom error pages, as I have a httpmodule for logging errors (this is a low traffic internal site, so wildcard mapping performance penalty is not a problem ;))
You need to add an HTTP Handler in your web config for gif files:
<system.web>
<httpHandlers>
<add path="*.gif" verb="GET,HEAD" type="System.Web.StaticFileHandler" validate="true"/>
</httpHandlers>
</system.web>
That forces .Net to handle the file, then you'll get the .Net error.
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /test.gif
Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433
You can try use custom errors to do this.
Go into Custom Errors in you Website properties and set the 404 to point to a URL in your site. Like /404.aspx is that exists.
With aspnet_isapi, you want to use a HttpModule to handle your wildcards.
like http://urlrewriter.net/
You can't use wilcard mapping without using ASP.net Routing or URLrewriting or some url mapping mechanism.
If you want to do 404, you have to configure it in web.config -> Custom errors.
Then you can redirect to other pages if you want.
New in 3.5 SP1, you set the RedirectMode to "responseRewrite" to avoid a redirect to a custom error page and leave the URL in the browser untouched.
Other way to do it, will be catching the error in global.aspx, and redirecting. Please comment on the answer if you need further instructions.
