Hello
Getting a web same page with 2 or more possible "states" eg business
part, private part or all parts, can you recommend a way to represent
the states via HTTP GET? Feasible way could be ?business=business, ?
type=business, ?business=true or others. Should I minimize casting the
variable? Which type should I reason, boolen or string? I now use
seemingly arbitrary ?t=w to represent a state which technically works
leaving a more readable and maintainable solution to wish.
Thanks

First, bear in mind that every data value you get from a web
interface is a raw string of bytes. You have no assurance that it is
a "Boolean". You're not even sure it will convert to "str" or
"unicode". It may legitimately contain "%" type URL escapes.
(Even if you think you control the URL format, a proxy, URL
shorterner, or other intermediary may do some format conversion.)
If you want to pass a "boolean" variable, I'd suggest sending
"http://www.example.com&val=t";. If you want to send False, omit
"val". On the read side, look for "val", and if the result
starts with "t" or "T", accept it as True. Otherwise, False.
