Redirect all traffic except crawler

[avav]

I have an ASP.NET website with a default.aspx page that ranks fairly high on google. Now - I am in the process of moving (redirecting) to a new landing page (index.php) - one that is under a subfolder /wordpress.

I would like to redirect all traffic to the new landing page. However, I also want my existing default.aspx page to continue to be indexed by google's crawlers - since I do not want to lose the high ranking the site has.

So - essentially - I want to redirect all traffic except the crawlers - the crawler still needs to index the default.aspx and not the index.php.

Any suggestions? Site is currently hosted on IIS7 and ASP.NET 3.5.

Thanks
AV

What you are looking at doing I think would be considered cloaking, and most crawlers frown on it.

As for redirecting all but google related bots, you will need to update your browser defintions, and do a little bit of coding for that if you want to do simple User-Agent based redirects. But google and most major search engines also operate stealth crawlers, which use a nonbot User-Agent to check for cloaking. You can ask Cloaking related questions in WebmasterWorld very on Cloaking forum [webmasterworld.com]

My advice is to a Perm Redirect 301 status code, from default.aspx in the root to /subfolder/index.php
