title: Manipulate or split string
body: <p>I've a quick question, that would solve me some problems if possible:</p>
  
  <p>Is it possible to split / manipulate the request-url with nginx?</p>
  
  <p>What I mean is: an url like this: sub.somewhere.com/something/somethingelse</p>
  
  <p>Is turned into:</p>
  
  <p>subsomethingsomethingelse</p>
  
  <p>And then further into:</p>
  
  <p>sub/som/eth/ing/som/eth/ing/els/e</p>
  
  <p>And then the given path is used to retrieve a File (so probably, it has to be stored in a variable that can be re-used, or used directly)</p>
  
  <p>Is this possible somehow? Or if not, what exactly would be possible, and where are the limitations?</p>
  
  <p><strong>(edit) Are there native possibilities to do this, whitout including the PERL Module? Or is that the only way? (maybe a smaller module that only does string handling? )</strong></p>
