Cache is your enemy

Browser cache is a phenomenal feature reducing http related traffic with 2 or 3 orders of magnitude, but during the development it can induce serious trouble. I mentioned some caching problems already in my previous post. This time I spent most of the day today hacking some nasty http-handshake problems just to figure out, that chrome is not properly rreshing my jQuery source. I arrived to the point where v8 had in memory two different versions of the same library (sic!). I have no idea how this is possible.
Apparently so-called "incognito" mode doesn't really solve the problem. The solution which worked for me was to disable cache in chrome developer tools.

Now that this works I can proceed with doing something more useful.
