Thanks for the 2 options. #1 would be cleaner and I think I avoided some of
its performance hit by running the logic in the Page_Init method before the
line InitializeComonent executed. I used a 'redirect' and 'return' before
InitializeComonent could run. However, I ended up using #2 as it seemed to
still be a wee bit faster (although I couldn't really tell by just watching
them both run).

Thanks for the help.
