Header modification with X-Accel-Redirect

[Brice Leroy]

My previous email was maybe unclear. I'm trying to log the bandwidth  
usage per clip I serve. because every clip are static file, I'm using  
x-accel-redirect to serve them. So I'm adding clip value to the header  
to log it using nginx with body_bytes_sent so I can know how much  
bandwidth has been used for this clip. But it seams that using  x- 
accel-redirect doesn't allow header modification because my log don't  
get the information. But if I remove the x-accel-redirect (of course  
in this case I don't get the file) the clip value injected in the  
header appear in my logs ! Any idea to make this value appear when I  
use X-Accel-Redirect ?

Thanks :)
