Epilogue And Ongoing Problems

Well, that's it!

There is one ongoing, lingering problem I'm experiencing that I thought I'd document here.

Once in a while, on Facebook, an image served up by Akamai won't load properly.
It appears as though a timeout occurs within the browser, and while Safari
will simply load the image later, Firefox won't.

Reloading the webpage in the browser seems to "fix" the problem but that's really
more of a hack than a solution.

I thought at first that this had to do with somewhat well-known problems regarding
Akamai and the HTTP VARY header, but I've seen it happen with VARY support both
turned on and off.

I plan to look into this further, and will update this Wiki page as necessaryAt this point I believe I've resolved any lingering problems, but of course only time will tell.
