header passed to fastcgi

[Daniele Melosi]

Hi all,

I notice that nginx when pass header to fastcgi add "HTTP_" at the 
beginning even if HTTP_ is already present like in the example below:

$ curl "http://127.0.0.1/daniele.php" --header "Host: localhost" 
--header "HTTP_TM_USER_ID: 36" --connect-timeout 3 | grep HTTP_TM_USER_ID
<tr><td class="e">_SERVER["HTTP_HTTP_TM_USER_ID"]</td><td 
class="v">36</td></tr>
<tr><td class="e">_ENV["HTTP_HTTP_TM_USER_ID"]</td><td 
class="v">36</td></tr>

Is it possible to avoid this and pass the header "as is" ?

Best Regards

Daniele
