Page cached even caching doesn't activated

Hi, I face an odd situation
When I edit file example in view
Like echo "blabla", I have to wait a couple of minutes (about 3-5 minutes) to get the change in my browser even I refresh it many times

It's like cache, but I don't activate cache feature
I also deactivate cache using max-age=0 in htaccess but still get the same problem, I then change to another browser but still get the problem

But when I move to another computer, the problem is gone

Its really frustating, and take lots of my time for just editing and debuging one function
