Do applets and browser share cache?

Question

I have a third-party applet that uses the csv file, called it file.csvand uses all the columns. I also have a third-party SWF object that uses file.csv, but uses only 20% of the columns. The initial solution was to use the same file for both, as this would simplify maintenance.

My question is, what is file.csvdownloaded by the browser once and gets shared from both the applet and swf OR are both the applet and swf downloading their own copy file.csv?

This is important because it file.csvis a large file, and if the user needs to download it twice, bandwidth will be saved when two versions are saved.

Using Firebug, CSV is displayed only once. However, when I remove swf, the applet still extracts file.csv, but it is not specified in Firebug.

Answer 1

Answering my own question, but further research showed that the applet and browser downloaded the file independently.
