ASM illegal meta character '!'
We are implementing ASM here at the site. We had enabled traffic learning and have got 5000+ suggestions. Majority of those suggestions comes under 'Illegal meta character in URL'. And the illegal character being referred to is the exclamation mark '!'.
I understand that I can include that as accepted character, but would like to know why F5 considers '!' as illegal when the RFC declares it to be legal character.
