Concurrency in reading and writing files

silvercover

Hi,

I have a website and part of my website needs to read/write a plain text file on server. most of the time we have between 50 to 100 concurrent online users and their actions on our site result to read/write certain file in which that is a temporary place holder for some other pages.

So I want to know about concurrent read/write conflicts and what's the best practice to avoid that if that happened. How does my server manage these requests?
