Question

I have a script that generates a new CSV file (in my web directory) every half hour, it replaces the original one and puts a new one in its place with the same file name, the file is linked to on my website.

When I download the file from my website, instead of getting an updated version I get a file that is the same as the first time I downloaded it on this computer.

My first thought was to make sure that the script is still running properly and after testing, I can confirm that it is.

I then cleared the cache and download history in Chrome and tried to download it again, this time it worked as intended.

I am running this off of a rackspace cloud server running ubuntu and apache. I assume there is some setting that I need to reconfigure to fix this problem. Could someone please point me in the right direction.

Thanks in advance.

A somewhat dirty solution is to append to the script that let you download the file a random number (or maybe the timestamp) as parameter to prevent the caching.

For example:

http://www.example.com/download.php?file=my.csv&rand=123456789
