Some user agents will work anyway, while others will choke. ( In other words, just because your browser seems okay doesn't mean GoogleBot will be. ) MSN sadly seem to have a brain freeze for a lot of things. My photo blog shows traffic from MSN for searches for dog pain killers. ( That could be clever referral spam...? ) Back to ASP and ASP.NET, while the latter allows HttpHandlers to use VB or C# code in place of ISAPI filters ... you can use some logic in a custom 404 page to manage your redirects. I tend to keep either a list of pages, or reg ex patterns, in an xml file or in the database, then have the logic in the 404 page scan that against the requested url before it decides what to do: send a 301 redirect, or a 404 error.

I don’t know about the other engines, MSN seems to have a brain freeze when it comes to handling simple things like this.

Be aware that PageRank doesn't appear to be passed through any sort of redirection chain like this. I am not in favour of a double redirect, but if you really have to, then this method should work.

I'd add <code>Response.End</code> because with a 301 header the user agent won't look at the content you output. Neat trick, John. I’d add
Response.End
because with a 301 header the user agent won’t look at the content you output.
