In certain circumstance it makes sense to control caching via the application. 
We have the following problem within KMyMoney (the following is a post from 
2006 so it's related to KDE3):

---%<---
The online quotes HTTP retrieval can hit KDE's cache and thus not retrieve the 
most current data.

Reproduce: KDE Control Center-Internet-Web Browser-Cache: Select "Use cache 
whenever possible".   Retrieve an online quote (in my case, 
http://finance.yahoo.com/d/quotes.csv?s=USDCAD=X&f=sl1d1).   Wait at least one 
working day so the quote file has been updated.   Get it with Firefox or some 
other browser to make sure it has been updated.   Retrieve an online quote 
with Kmymoney - get the previous day's data, because it has been cached.   In 
Control Center-Internet-Web Browser-Cache, select "Clear cache".   Retrieve an 
online quote - get the current data, because the file is no longer in cache.

Developers who use konqueror routinely or have caching turned off wouldn't 
observe this, because the quote file likely wouldn't be cached the second 
day.   But for the users who don't use konqueror (and don't reboot their 
machine or otherwise clear the web cache), they can't update their online 
currency quotes because the old data will stay in cache.

Just another 0.02
