Automatic URL rewrite in .htaccess

At first I used IIS server for PHP, so I'm new to Apache (Windows platform). I am in some puzzle related with URL rewrite. As in my .htaccess file I use the below code for URL Rewrite.

Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.*)\.aspx$ $1.php [nc]

Now If I browse a .php page with .开发者_JAVA技巧aspx extension, it works well. eg If I browse

www.example.com/guwahati.php => www.example.com/guwahati.aspx (both URL works.)

But I want it automatically. Like if I type www.example.com/guwahati.php, it will automatically convert to www.example.com/guwahati.aspx, is it possible ? also URL rewritting is not working on my localhost. may anyone help me please.

It is possible, but by using redirect headers, not URL rewrites. Actually you could do an URL rewrite that redirects to a single file that replaces the target extension with aspx and then redirects to it. You may need to enable mod_rewrite in order for it to work.
