How to break URLs when footnotes are on same line?

Question

Question Footnotes on the same line revealed that it is a good idea to use \usepackage[para]{footmisc}. However, this does not seem to work with URLs:

\documentclass{article} 
\usepackage{hyperref}
\usepackage[para]{footmisc}
\begin{document} 
test\footnote{\url{http://www.example.org/long-URL/long/long/long/long/long/long/long/long/long/long/long/long/long/long/long}}
\end{document}

The given URL is not wrapped (but footnote 2 and 3 are on the same line). If footmisc is not loaded, the URL is wrapped perfectly. What can I do if I want to use footnotes with URLs next to each other?

More complex example (following answer https://tex.stackexchange.com/a/56706/9075):

\documentclass{article} 
\usepackage[para]{footmisc}
\usepackage{hyperref}

\def\myurl#1{\setbox0\vbox{\hsize.5\maxdimen
\url{#1}\par
\global\setbox1\lastbox}\unhbox1 }

\begin{document} 

test\footnote{\myurl{http://www.example.org/long-URL/long/long/long/long/long/long/long/long/long/long/long/long/long/long/long}}

ODE\footnote{\myurl{http://ode.apache.org/}}). 
SOAP/http\footnote{\myurl{http://www.w3.org/TR/soap12-part2/}} 
\end{document}

The output is as follows:

I'd like to have footnote 2 and 3 on the same line

Answer 1

To make it work with para automatically you need a modified version of \url

as noted in the comments, you the first version added parfillskip glue after each url which padded to the end of the line, This version removes that.

\documentclass{article} 
\usepackage[para]{footmisc}
\usepackage{hyperref}

\def\myurl#1{\setbox0\vbox{\hsize.5\maxdimen
\url{#1}\par
\setbox0\lastbox
\global\setbox1\hbox{\unhbox0\unskip\unskip\unpenalty}}\unhbox1 }

\begin{document} 
test\footnote{\myurl{http://www.example.org/long-URL/long/long/long/long/long/long/long/long/long/long/long/long/long/long/long}}

ODE\footnote{\myurl{http://ode.apache.org/}}). 
SOAP/http\footnote{\myurl{http://www.w3.org/TR/soap12-part2/}} 
\end{document}

Answer 2

If you remove the [para] option for footmisc, every thing works smoothly.

\documentclass{article}
\usepackage{footmisc}
\usepackage{hyperref}
\begin{document}
test\footnote{\url{http://www.example.org/long-URL/long/long/long/long/long/long/long/long/long/long/long/long/long/long/long}}
\end{document}

Edit: If you want to keep the para option for footmisc, we can pass the option [obeyspaces,spaces] to url (loaded by hyperref) and give a space where the line has to be broken. Since there comes an option clash between footmisc, we pass it to the documentclass.

\documentclass[obeyspaces,spaces]{article}
\usepackage[para]{footmisc}
\usepackage{hyperref}
\begin{document}
test\footnote{\url{http://www.example.org/long-URL/long/long/long/long/long/long/long/long/long/ long/long/long/long/long/long}}
\end{document}
