I have an app that works with tidy CSV files.
By chance I prepared two files that are almost identical. All that changed was the name of one column.
If realized that if I open one file, and then I rerun the app and open the other file, the cache does not “see” the difference, thinks that it is still the first file (that has a different column name) and the app fails.
I guess this is more a curiosity than a real problem because (i) probably files will be more different than this and (ii) maybe using the uploader widget to load a new file automatically “tells” the cache that there is a new file.
However since my two files are (a tiny bit) different, they should have a different hash, and I was surprised that I had fooled the cache.
Thanks for the great product
