IE "friendly" errors workaround

I decided to do some digging into IE's "friendly" error issue, and came across [this MSDN article](http://blogs.msdn.com/b/ieinternals/archive/2010/08/19/http-error-pages-in-internet-explorer.aspx) addressing the problem. They suggest padding the response with whitespace until the 512 byte limit has been reached, as a way of preserving the usefulness of the HTTP status codes (and without forcing users to change their settings... since I think if users felt comfortable doing this they would probably not be using IE). Would be nice to note this alternate solution in the docs.

Side note: I have "trim trailing whitespace" set in my editor, and noticed that most lines in the readme (and other files) seem to have a bunch of extra whitespace. Any reason for this? Personal preference?
