So I'm running nightly tasks to generate some custom statistics for my site and copy the statistics in .csv format to separate server via SCP. Then I use these .csv files in Google Sheets to display them in table format.
The problem is, though, that each time I load the .csv file I need to give that spreadsheet "hard refresh" so it wouldn't use "cached" browser data when displaying the .csv file.
Is there a possibility to refresh the data each time opening the document?
i would suspect that setting the expire-time for the .csv file could help. that would be something for the server to deliver.
OR you can trick the webbrowser by appending something random at the end of the url you are using to fetching the data (see my comment on your question):
http://example.com/myfile.csv?_invalidate_cache_of_browser_XYZ
and then you have to put some random XYZ into the url, maybe by usuing the rand() function.
Unfortunately the solution suggested by akira doesn't always work. Google will not republish the Spreadsheet data immediately until the next "publish" cycle. So what this means is that it is not a browser caching issue.
