These are the docs for X-Accel-Limit-Rate :
Sets the speed limit for this single request. Off means unlimited.
Not so much. Most of the examples (I found only two or three), I saw that the value of X-Accel-Limit-Rate is 1024. This is obviously 1024 bytes, but for what? Or is it something of a sort?
Not knowing what meaning means is hard to understand what it actually does. If anyone knows, I would be very grateful.
