Yeah I now how to 301 redirect. The problem is to do it with default.aspx,
without causing an infinite loop. The homepage has 2 url's
www.eample.com/default.aspx and www.example.com. I want to 301 redirect
anyone who get default.aspx in the url.
Request.RawUrl returns default.aspx in both cases, so i can't figure out how
to check if the user has default.aspx in his url.

I use request.Url.AbsoluteUri which seems to work fine unless I pass a
parameter in the query string.

I've tested your sugestion. I get the same problem:
If I write Response.Write(Request.Url.AbsoluteUri ) in the pageload of
Default.aspx i get http://www.example.com/deafult.aspx even if the url in
the browser says www.example.com
If I write Response.Write(Request.Url.AbsoluteUri ) in the pageload of
Default.aspx i get http://www.example.com/deafult.aspx even if the url in
the browser says www.example.com

You don't have to issue a 301...
Your request sounds like a job for Ionic's ISAPI Rewrite Filter, but you'll only be able
to use it on a server you control. Shared hosters seldom let you install ISAPI filters.
IIRF :
http://cheeso.members.winisp.net/IIRF.aspx
It's free.
To remove default.aspx from the URL, you'd use :
RewriteRule (.*)/default.aspx$ $1/ [I,RP]

Thanks. I was hoping to find a solution without using ISAPI filter, but I
guess that is the only option, or wait till IIS7 is available.

You can do this in an httpmodule
Here's one I wrote that uses a table in a database to match and replace.
It will handle 404 errors as well as being pre-emptive. It will either
do a 301 redirect or RewritePath (based on flag in db)
Table Schema:
OldUrl : varchar(n) - RegEx match or literal (based on field below)
NewUrl : varchar(n) - literal url to redirect to
Redirect301: bit - true if 301 redirect, false if RewritePath
Literal: bit - specifies that the OldUrl is a literal value and not a
pattern match.

Yes, that's what I initially thought, too, but ran into a wall.
Have you actually tested that ?

Conversation: How to 301 redirect default.aspx to root
Subject: Re: How to 301 redirect default.aspx to root
Thanks. I was hoping to find a solution without using ISAPI filter, but
I
guess that is the only option, or wait till IIS7 is available.

You don't have to issue a 301...
Your request sounds like a job for Ionic's ISAPI Rewrite Filter, but
you'll only be able
to use it on a server you control. Shared hosters seldom let you install
ISAPI filters.
IIRF :
http://cheeso.members.winisp.net/IIRF.aspx
It's free.
To remove default.aspx from the URL, you'd use :
RewriteRule (.*)/default.aspx$ $1/ [I,RP]

Yeah I now how to 301 redirect. The problem is to do it with
default.aspx, without causing an infinite loop. The homepage has 2
url's
www.eample.com/default.aspx and www.example.com. I want to 301
redirect
anyone who get default.aspx in the url.
Request.RawUrl returns default.aspx in both cases, so i can't figure
out
how to check if the user has default.aspx in his url.

If i recall correctly, can't you just set this up in IIS, i just
googled
"301 redirect" and got
http://www.webconfs.com/how-to-redirect-a-webpage.php as the first
link...

How can I 301 redirect www.example.com/default.aspx to
www.example.com
without using ISAPI filters?
