Uri generic syntax (RFC 2396)

Uri generic Syntax:

 

Uric = reserved | unreserved | escaped

 

Reserved = ";" | "/" | "? "|": "|" @ "|" & "|" = "|" + "|
"$" | ","

 

Unreserved = alphanum | Mark

 

Mark = "-" | "_" | "." | "! "| "~ "|" * "|" '"|
"(" | ")"

 

Escaped = "%" hex

 

Hex = digit | "A" | "B" | "C" | "D" | "E" | "F" |
"A" | "B" | "C" | "D" | "E" | "F"

 

Alphanum = Alpha | digit

 

Alpha = lowalpha | upalpha

 

Lowalpha = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" |
"J" | "K" | "L" | "M" | "N" | "O" | "p" | "Q" | "R" |
"S" | "T" | "U" | "v" | "W" | "X" | "Y" | "Z"

 

Upalpha = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" |
"J" | "K" | "L" | "M" | "N" | "O" | "p" | "Q" | "R" |
"S" | "T" | "U" | "v" | "W" | "X" | "Y" | "Z"

 

Digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" |
"8" | "9"
