So today I was trying to determine why a dynamically generated PDF file was not accepting changes when the user clicked submit. The PDF file was being spawned in another window but the values did not change. The problem only occurred when using IE, all other browsers worked fine. Turns out that IE decided to handle caching differently. The solution to the problem was to append some random junk at the end of the URL. I added the date and time and amazingly it worked without issue. IE, I have had to work around you way too much in the last week. I am not happy with you.
