Hi Guys,

I did a little further investigation. I found that the order of 2 server
blocks matter in my case.

If I put the /_x_accel_redirect/ block first, then the 2nd proxy server
block is not effective.
If in the order I pasted in the previous message, then the
_x_accel_redirect block is not effective.

But why is this? btw I'm using the 1.1.19 version of nginx that comes with
ubuntu.

Could anyone give me a hint? I'll be really grateful.

Thanks,
Rui
