title: how to make web framework based on Python like django?
body: <p>I'm just wondering what knowledge or techniques are needed to make a web framework like django. </p>
  
  <p>so the webframework is able to serve as a cloud computing (a website can be scaled horizontally by sending some stuffs that must be solved to other server.) when needed, and can be used to build a website fast like django if a developer want to build a just simple website.</p>
  
  <p>Sorry. my English is very awkward cause I'm an Korean.</p>
  
  <p>just give me some approaches or instructions about what techniques are needed to build a web framework or what I have to do or learn. </p>
  
  <p>Thanks a lot. </p>
