I'm not sure exactly what I'm looking for. I know unicode is basically any character besides the alphabet. I checked the two sites in the FAQ and it seemed to make things more confusing. To be more exact, this is what I want to learn.

What do these do????!???

/..%c0%af../

cmd.exe?/c+dir+c:\

/..%c1%c1../

/..%255c..%/

(and I'm sure there are many more)

Now I'm not trying to deface webpages with the infamous IIS exploit. I just want to know two things. What do these commands do? Where can I read about them? (because I have had no luck on google.

thanks fellas

sorry for such a newb question, I feel bad for asking it.
