php - Apache2 SetEnvIfNoCase using Request_URI -

i'm trying set locale environment variables in vhost on apache server, requested path define locale used. requirement use more "consumer friendly" locale code, rather iso format - need map supported iso format in framework.

for example: http://site.com/uk/path/to/page.html set environment variable of req_locale=en_gb

and want default english if unexpected locale found.

what i'm trying use @ moment apache setenvifnocase directive in manner:

setenvifnocase request_uri     ^/eu     req_locale=en_us setenvifnocase request_uri     ^/es     req_locale=es_es setenvifnocase request_uri     ^/de     req_locale=de_de setenvifnocase request_uri     ^/fr     req_locale=fr_fr setenvifnocase request_uri     ^/it     req_locale=it_it setenvifnocase request_uri     ^/uk     req_locale=en_gb setenvif req_locale      ^$       req_locale=en_us 

for reason last directive being called. if remove ^/ regexes de 1 always called.

so.. i'm @ bit of loss :)

can help? (nb: i've tried using request_uri request_uri - no change in result)

edit think following rewrite rule causing issue:

rewriterule .* index.php [l] 

looking @ rewritelog - seems causing redirect , environment variable isn't being carried across. so...

use this:

# initialize env var en_us setenvifnocase request_uri     "^"     req_locale=en_us  # set conditionally setenvifnocase request_uri     "^/eu"  req_locale=en_us setenvifnocase request_uri     "^/es"  req_locale=es_es setenvifnocase request_uri     "^/de"  req_locale=de_de setenvifnocase request_uri     "^/fr"  req_locale=fr_fr setenvifnocase request_uri     "^/it"  req_locale=it_it setenvifnocase request_uri     "^/uk"  req_locale=en_gb 

edit: can chanege rewrite rule this:

rewritecond %{query_string} ^$ rewriterule ^ index.php?lc=%{env:req_locale} [l,qsa]
