htaccess重写规则配置

Question

I would like to configure htaccess rewrite rules but have some difficulties.

My rule is simple:

DOMAIN/SL --> index.php?lang=SL
DOMAIN/EN --> index.php?lang=EN
DOMAIN/IT --> index.php?lang=IT
DOMAIN/DE --> index.php?lang=DE

so I added in htaccess simple rule:

    RewriteEngine On
    RewriteRule ^([A-Za-z0-9]+)/?$ index.php?lang=$1 [L]

and it is partial working.

Works if I type

  DOMAIN/SL 
  DOMAIN/IT 

Doesn't work for

  DOMAIN/EN 
  DOMAIN/DE 

For those two generates

  /DOMAIN/EN/?lang=en or /DOMAIN/DE/?lang=de 

and I don't know why.

Is it DE or EN some reserved word or what?

Answer 1

I believe this should work, as you wish for it to do.

RewriteEngine On
RewriteRule ^([A-Za-z]{1,})/?$ index.php?lang=$1 [L]
