Add it so that if we select a directory without index.html, then we send
  directory listing.
if enter in / and no /index.html then don't print out //index.html!
  get rid of extra /
if we added /index.html at end and it resulted in non-existant file,
  remove /index.html from end to show original request.
Don't send redirection if the redirection will not result in a found file!
Add the HTML headers (conformity ones) to regular files that are 
  sent over to browser. not just error/redirection messages.
