JavaScript file not updating no matter what I do

Question

I have an external JavaScript file and whether in FireFox or Chrome, whether all browsing data is cleared, it will NOT update no matter what. I believe something happen

Answer 1

The best way around browsercaches is to append a random number to the path of the js file.

Example in pseudo code:

// generate a random number
int i = Random.Next();
echo "";

This will make sure your browser always reloads the file, because it thinks it's a different file because of the random number in the url.

The server will always return the file and ignore what comes after the '?'.
