d3 Caching Issue

[Gregory Sloggett]

Hi, 

I'm trying to do a simple CSV bar chart, which takes in user input, writes it to the CSV file, and updates the graph on my webpage. 

The issue I'm having is cache related, as the graph doesn't update when the user submits there details, even though the CSV file has been updated. When I clear the cache on my browser, the graph is then updated. I would like to prevent this hassle for the users experience.

I'm developing in Python-Flask, and the issue has been on most browsers. Any suggestions?

Thanks in advance, 

Greg.

Some options

- append a question mark + random number (?12312414) to the requested CSV url. 

- send proper cache control headers

- if you are on apache update the main config or modify htaccess

The random number worked perfectly for me, thanks Ibrahim!
