Extra slash in URL

[cmonkiew]

Due to an extra slash in the URL I get a 404 from my server.
Sample code:
server = Redmine('https://foo.blargh/redmine')

When I do this the code tries to access https://foo.blargh/redmine//projects.json

On our web server:
https://foo.blargh/redmine/projects.json works
but
https://foo.blargh/redmine//projects.json results in a 404
