Hello,

I have a problem with my configuration and i need your help please ;)

I have the following URL that points to my nginx : http://blablabla/folder/cmm/200/aHR0cDovL2F6MjMyNjIudm8ubXNlY25kLm5ldC90cGltYWdlcy81OGE0NTVlNjYzYzNmYmM2OWMwYThjMTJlMGIwYzllOF9taW5pXzguanBn.jpg

I need to extract the following section (it's Ok): aHR0cDovL2F6MjMyNjIudm8ubXNlY25kLm5ldC90cGltYWdlcy81OGE0NTVlNjYzYzNmYmM2OWMwYThjMTJlMGIwYzllOF9taW5pXzguanBn

Then do a decode_base64 of this string extracted (it's Ok): http://az23262.vo.msecnd.net/tpimages/58a455e663c3fbc69c0a8c12e0b0c9e8_mini_8.jpg

And for finish, do a proxy_pass to this new URL (with addition in the cache)

****************** Here is my code ***********

location /folder {
if ( $uri ~ "^/folder/cmm/200/(.*)\.jpg" ) {
set $filename $1;
set_decode_base64 $url_partenaire $filename;
#echo "$url_partenaire"; => print : http://az23262.vo.msecnd.net/tpimages/58a455e663c3fbc69c0a8c12e0b0c9e8_mini_8.jpg
proxy_pass "$url_partenaire";

however I'm stuck at this stage now
