是否可以使用.htaccess将六位数的URL发送到脚本，但将所有其他无效的URL作为404s处理？

Question

Is it possible to use .htaccess to process all six digit URLs by sending them to a script, but handle every other invalid URL as an error 404?

For example:

http://mywebsite.com/132483

would be sent to:

http://mywebsite.com/scriptname.php?no=132483

but

http://mywebsite.com/132483a or
http://mywebsite.com/asdf

would be handled as a 404 error.

I presently have this working via a custom PHP 404 script but it's kind of kludgy. Seems to me that .htaccess might be a more elegant solution, but I haven't been able to figure out if it's even possible.

Answer 1

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteRule ^([0-9]{6})$ scriptname.php?no=$1 [L]
</IfModule>

To preserve the clean URL

http://mywebsite.com/132483

while serving scriptname.php use only [L]. Using [R=301] will redirect you to your scriptname.php?no=xxx
