Redirects - .NET Framework

Stan Canepa

I have a web app that works fine on the development machine and on several
servers running Win2k IIS 5 and Windows2003 IIS 6. But I am having an issue
on one particular erver running Win2k IIS 5, but has an Apache server
sending redirects to this server.

My problem is when I try to do a

Response.Redire ct ("~/somepage.aspx")

The page calling the Response.Rediec t is in the same directory as the
somepage.aspx, but I get 404 Page Not Found Error. This happens everytime.
The test app I was working with was as simple as having two web forms, and
in the page load of the first have the redirct to the other.

Another piece of info that may be of relevance is that the web app is
running on port 90 because the Apache runs on 80. The Apache configuration
file looks something like

Proxypass /dw/ http://machine.company.location.md.us:90/
ProxyPassrevers e /dw/ http://machine.company.location.md.us:90/

So www.mainsite.com/dw/ would redirect to my server using port 90.

Also the application runs fine if ran from the server itself. I only have
the problem when accessing the app over the internet through the Apache
server.

Any help would be greatly appreciated.

Thanks

when you use Response.Redire ct, by default asp.net generates a fully
qualified url. in your case

Response.Redire ct ("~/somepage.aspx")

returns:

http://machine.company.location.md.u.../somepage.aspx

which is bypassing the proxy. you should turn off fully qualified redirects
in the HttpRuntimeSect ion. once you turn it off I don't believe ~ operator
will work, you will have to do relative redirects.

Running a proxy like Fiddler (www.fiddlertool.com) should reveal the problem.
What I think happens is that
Response.Redire ct ("~/somepage.aspx")
produces something like
HTTP/1.1 302 Found
Server: Microsoft-IIS/5.1
Date: Fri, 17 Mar 2006 17:44:04 GMT
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Location: /<YourApplicatio nRoot>/somepage.aspx

That would be wrong: It doesn't access the rewritten path /dw/. I can actually
create a similar issue by just using another redirection virtual directory
in IIS. The fix is to create the redirect location manually.

Are you sure? According to MSDN and my own observations, it's set to false
by default. Anyway, it's a better approach than constructing the URL manually,
but there may be situations in which it cannot be avoided.

I was looking information up on
HttpRuntimeSect ion.UseFullyQua lifiedRedirectU rl and have found that it is
new to the .Net Framework version 2. The site was written in VS 2003
framework version 1.1.4322. I have a feeling you are right about the path.
Any other ideas about how I might go about fixing the issue? Do you think
Transfer would work?

How to: Binding redirects across multiple appdomains

by: David Levine | last post by:

This may be an easy one (I hope so). The ultimate goal I have is to be able to use binding redirects that are specific to secondary appdomains, so that each appdomain can have a unique configuration. Here's are the details: I want to force all references to a particular assembly version to use the latest version of the assembly. I can do this by adding binding redirects to the app config file and in a test I did it all works fine.
