Hi guys. May be my question will break your nerves but please forgive me. At first I love Nginx. Nginx is dream come true for poor student like me :)) which doesn't have money for sloooooowly web servers for my projects :)). So, BIG thanks for Igor and all of you guys who contribute beautiful code for this project. You are awesome!

However, my question ofcource :) Can you tell me guys how I can check for existing remote file.
What i mean:

10x in advance.
