EDIT: this is very sad that almost 5 years after I wrote this answer - it is still true. If you can, look at the history of this answer.
EDIT2: I found a better answer on StackOverflow - What is the maximum length of a URL in different browsers?
EDIT3: 9 years after - Explorer is deprecated in favor of Edge, Edge soon to be re-designed using Blink (making it very close to Chrome). I wonder how relevant this answer is.
Problem
What is the character limit for a URL, especially if the URL is formed from a GET method of a form.
