    Hi Kiosk,

    a syntax of...

    HTTP::uri [string range $uri 4 end]

    ... means that you will set the currently requested URI to a new value with a string range from the 

    5
    character to the 
    end
    of the variable 
    $uri
    . (Note: the 
    4
    is the number of character to left out from the beginning)

    Example: If the variable 

    $uri
    is 
    /abc/xyz/file.ext
    then 
    HTTP::uri
    will become 
    /xyz/file.ext
    after this command. The leading 
    /abc
    (aka. 
    4
    chars) of 
    $uri
    will be stripped...

    Cheers, Kai
