how to htaccess redirect form www.mysite.com/* to www.mysite.com/

On my site google indexed www.mysite.com/* which isn't on my server.

This URL came from some other external source and it's causing a 404 error.

So I开发者_Go百科 want to redirect this URL to my homepage.

How can I achive that?

You could do a 301 redirect to your homepage. Search engines will then learn from this and eventually the listing will be removed.

Redirect 301 old-page.htm index.htm

Add the following value to your .htaccess

ErrorDocument 404 /index.php

Or .html is you're index is a .htm or .html file.
