Hi some,
I'm really not sure what's wrong with your code, except that for some reaso=
n the slash in
requestPath :=3D "/index.html" seems to be really confusing the Io vm. If y=
ou remove it, your prints should work and requestPath should be reassigned =
as you wish. Io's web handling appears to automatically prepend the root di=
rectory to the beginnings of requests.

^-- h=
ere's your problem, delete that slash and all should be well.
As an aside, since requestPath has been instantiated already you could writ=
e
requestPath =3D "index.html" instead of requestPath :=3D "index.html". It s=
houldn't make any difference, but the :=3D is only required when you create=
an object, but isn't necessary for assigning a new value to it.
> requestPath print

^-- for whatever reason, this line doesn't seem to print until another requ=
est is made, so it comes out before all the header info of the next request=
rather than after the header info of the request it's referring to.

Should work now. I hope this helps.
Best,
