seo url and routes.php

[eluser]Bad Penguin[/eluser]
The $route['en']
will match both /en and /en/
leading to duplicated content if someone type or link me with the wrong url

how can i match "/en/" url only so i can redirect it to controller "homepage/index/en"
and match "/en" so i can redirect it to different controller "redirect/homepage/en"
?

Thanks in advance

why would you want to redirect to different urls?
use .htaccess to solve trailing slash problem

I'm perfectly aware about using mod_rewrite, you didn't understood my problem: i don't need to redirect to different urls.

For some reason i've "strange" incoming queries that leads to duplicate pages.

As example if my url is: /de/
then for some reason i get spidered for more other urls too:
- /de (no trailing slash)
- /de.html (because my suffix is .html this will become "de" in codeigniter)
- /de/.html (because of my suffix this will become "de")

I already used linklint to check my whole URL navigation tree and is not broken.

But this is not only the /de/ case, it also apply to /en/category1/tag1/ and any other URL i've.

I need codeigniter to respond to exactly only the URLs i've and that i want,
perhaps i should remove $config['url_suffic']='.html'; and use regular expressions in routes.php?

Or this is a core limitation by design of codeigniter and if i want a more SEO friendly routing system i need to use some different tool?

I believe this is done by the webserver and it does it to url's that do not have a file extension associated with them because traditionally those are directories.

In other words, http://www.yoursite.com/something would be considered a directory where http://www.yoursite.com/something.html wouldn't. If it thinks the url is a directory, it (webserver) tries to add a slash to the end. This isn't unique to CI.

A solution is to add this to your .htaccess. It will 301 redirect anything ending in a slash to the same thing without the trailing slash, so that only 1 url will work for each page.

Code:

RewriteEngine On
RewriteRule ^(.+)/$  /$1 [R=301,L]

As i wrote, this does not solve anything, it still generated duplicated page
when .html extension is added and C.I. generates the same duplicated page.

Have you tried:

Code:

$route['en/'] = 'redirect/homepage/en';
$route['en'] = 'homepage/index/en';
