No particular reason to not include a form, just that this particular page
doesn't need one. I have no controls on this particular page.
My alternative is to create some kind of code that will figure out on the
fly where the debugfloat.js file is in relation to the current page and set
the scr in a javascript tag.
All of my pages are inheriting from ASPCommon.cs and I wanted to be able to
load the js script without having to add HTML to each aspx page. This js
file is only needed when my Debug class is enabled, and it's only going to
be for my IP address. I don't want the js file included for anyone else.
This will go on the production server so that I can more easily troubleshoot
problems. Because I don't want it showing up when Debug is disabled, I
wanted to add it dynamically to the page. I'd really like it to be added
inside the HEAD tags, but haven't figured out a way to do that yet.
Any other ideas?
