I'm rebuilding my site and with google i'm getting a load of requests
for .php or .aspx files which the previous site was built on.
Is there any way of redirecting these www.mysite.com/index.aspx
to the /index action via the routes, maybe a wildcard, so google
sitemaps doesn't list those old links as errors?
You could do this via a mod_rewrite rule, or if you just want rails to
accept those urls, you should be able to do that by adding a pseudo
mime type (in the same say that you can do to yourapp/orders.xml and
get an xml representation, you should be able to add pseudo types for
php and aspx that just behaved the same as the html ones)
