Problem using open-uri for loading from host:8080

open-uri (and the libraries it builds on) don’t seem to be able to
load resources from hosts with alternate port numbers.

I 'm getting a OpenURI::HTTPError: 500 Internal Server Error when
using open-uri to load from the following location:

r = open(‘

If instead I load it from a host without the 8080 port it works fine:

r = open(‘Teemss2’)

Any ideas on where the problem is?

For now I am working around this by using curl through a shell:

r = curl -s pedagogica-emf.jnlp
