Noob rx tx question when using vnstat
Don't knwo if this is the right place for me to ask this but I'm a bit confused. I'm using vnstat to measure my bandwidth usage, and I really do not understand what how the RX and TX stats show me my data. I understand that RX is download and TX is upload, but who's, when a user request a webpage from my server the server is than uploading the content, but my upload stats are extremly low it's like my server is not serving anything, but on the other hand, my RX stats show large download amounts. I just do not get it or my brain has just stopped working. Any one to help me?
