[Newbies] String asURI contentStream - troubles

[Petr Fischer]

Hi,

I need to get stream from general (user entered) URI.

1) 'file:///Users/pf/Documents' asURI contentStream - this works  
(instance of StandardFileStream)

2) 'http://www.seznam.cz/' asURI contentStream - error  
(MessageNotUnderstood: HTTPClient class>>contentStreamForURI:)

I need one way (method) for all types of URIs (http, file, ftp...).

Any ideas? Thanks, pf
