Forcing reload of remote text file for reading

1

I have been using this to read a file on the server which works fine:

req = ReadFile(filename, "Post");

My understanding is that the ‘Post’ parameter forces a read rather than loading from cache. Also, POST is being deprecated so I have been trying the ‘ReadFile’ sample. However, when I modify the remote file, the code still ‘remembers’ the old version unless I clear the cache in Chrome.
Am I missing something or is there a way to force a fresh read of the file each time the function is called. All I want to do is read and write a text file to the server. It may be modified by me but needs to be read afresh by several other users.

If the URL is one that the browser has in its cache, it will return the cached version. The trick is to make the URL you are requesting unique, by doing something like this:

url = "/manage/update_position/?nocache="+Math.random()

Another way to do this is to use the Ajax() function. It’s a wrapper for the jQuery $ajax() function, which has a cache=false option.
