Codeigniter and RewriteRule problem

I've been puzzling over this none for a while. This is the rewrite rule that I've got at the moment:

Options +FollowSymlinks
DirectoryIndex index.php

RewriteEngine on
RewriteRule ^ext\/(.*)$ index.php/cproposal/key/$1 [NC]

Essentially I'm trying to get

http://localhost/cvc/ext/12445345346

to rewrite to

开发者_如何学运维http://localhost/cvc/index.php/cproposal/key/12445345346

Codeigniter is producing a 404 however. If I change the index.php/cproposal/key/$1 part of the rule to something inane like the Codeigniter license.txt thats found in the directory then it works but anything actually related to Codeigniter itself produces a 404.

Any ideas where I'm going wrong?

mod_rewrite is great, but Codeigniter already has a built in solution for anything in your Codeigniter application.

Try adding this to your config/routes.php:

$route['ext/(:num)'] = 'cproposal/key/$1';

This would route requests for:

http://localhost/cvc/ext/{any_number}

to

http://localhost/cvc/cproposal/key/{requested_number}

The index.php will be optional, and dependent on your CI configuration. In other words, if you're using it already - it will be in the url. If not, it doesn't have to be.

All CI routes may use regular expressions in addition to the built in wildcards (:num) and (:any), so feel free to get creative.
