page 13, the input split in parseRequest assumes that there are two parts after the split.
I am not sure what would be "correct" and still concise, it just stood out to me as not being a very functional approach.

let parseRequest (input : System.String) = 
    let parts   =   input.Split([|';'|])
    let rawType =   parts.[0]
    let route   =   parts.[1]
    match   rawType with
    |   "GET"   ->  {Type   =   GET;    Route   =   route}
    |   "POST"  ->  {Type   =   POST;   Route   =   route}
    |   _   ->  failwith    "invalid    request"

  and after it "kitty" instead of "kitchen". Or is it a common shortcut for it?

@mofus I agree and it is not a robust request parser. I did this intentionally as the focus of the chapter, is just to get a feel of Suave and also to keep it simple. Thanks for the comments.

@vilinski Thanks for the finding. It is because of the parenthesis in the URL. It's fixed now.
