title: Slash in parameter Django
body: <p>I'm using Django as a restful api, and i have urls like                        <code>url(r'^datavore/(?P&lt;configuration&gt;.*)/(?P&lt;dataset&gt;.*)/(?P&lt;varname&gt;.*)/(?P&lt;region&gt;[a-z-A-Z\_]+)/(?P&lt;date_range&gt;.*)/filelist/$', views.filelist,name="filelist"),</code></p>
  
  <p>my problem is when the dataset parameter contains '/' it modify the structur of my url the dataset parameter contains only the string after the / . Any idea how to fix this ? </p>
