Fetching Character / Fetching Results happens on back - Why? No caching?

I noticed while navigating through the site and getting used to the layout that FN appears to completely ignore browser caching.

If I'm clicking through a user's gallery to view their submissions it refreshes each and every time I click back, displaying the "Fetching Character" or "Fetching Results" notification. I could just open everything in a new tab, but that's not the point of this question.

I get that there's an advantage to always pulling the latest information, but I would argue the disadvantages outweigh the advantages in this case, at least for user galleries. The front page is the only place I can think a lack of browser caching would be arguably useful.

Beyond the increased data usage, it creates an extremely sluggish user experience.

Thinking on this more I think I even have an idea to post... but this question still stands.

Putting this in Questions instead of Bugs as I'm guessing it's a conscious decision.
