Formating a website name

[Evan]

Often I seen websites that use
letter not acceptable in windows
so IE5 changes the name and I
want to know the method it uses
I cant figure it out.
It replaces ":" with "%3a"
and "/" with "%2f"

Some characters aren't allowed in URLs because they are part of the URL syntax. I believe what you're seeing are the hex versions of these characters as they use the hex versions to get around this. Another example is the space. You can't have a space in a URL 'name' so you often use %20 (although sometimes you can use a '+'). I think it has more to do with the way URLs are formed and handled than with what Windows wants.
