I read about ajax calls and I thought that ajax calls was the solution to my problem in creating a chat room. After I had read the tutorial carefully, I tried to write my own ajax call code and when i uploaded the file to a free server it didn't work. I thought that maybe the code was wrong, but when i read it again it was correct. So I went to the tutorial and I copied the example code that I knew it was working. I created all the necessary files for the example to work, but again nothing happened. What I am trying to do is to access a txt file and read its content. Another thing with my server is that when i try to access a txt file, a white blank page is the result, when in other servers when I access a txt file i get the content of the file. My question is: Is it possible that a server does not support ajax calls?
