Internet Explorer Caching CSV file

Question

I have created a chart which updates whenever a csv file changes. It displays correctly in Firefox but in Internet Explorer it caches the csv file and only displays the correct value when the browser is refreshed. I have put the following into the header but it still dosent work

Is there any way to stop Internet Explorer caching the file.

You could append a random query string to the URL:

http://www.foo.com/ajax/data.csv?cdcvhygvfghjguytdrtd

(changing it for each request)

Hi Richard the link you posted does not work can you please re post – user3508973 Apr 10 '14 at 17:44
It wasn't meant to work - it was an example of using a query string. – Richard Apr 10 '14 at 20:41
This is what I am using to call the CSV file $(document).ready(func = function () { RGraph.CSV('/OfficeThermostat.csv', function (csv) Where should I add the string could you please give me an example – user3508973 Apr 11 '14 at 11:00
Add the query string to the filename as in the example I gave. – Richard Apr 11 '14 at 15:01
Is it possible to add a time stamp to this string – user3508973 Apr 11 '14 at 17:16
It would be even better If I could add a filetime as then the page would only update when the file changes is this possible – user3508973 Apr 11 '14 at 18:13
Yes you can use a timestamp eg a unix timestamp: foo.csv?1397298984 – Richard Apr 12 '14 at 10:36
Richard many thanks for your help and patience unfortunately my knowledge of coding limited would it be possible to explain exactly how I would add this timestamps to the URL – user3508973 Apr 12 '14 at 17:00
