  Neeraj Kumar: If a #webmaster redirects websitecom to websitecom/index, websitecom/index to websitecom/home and then websitecom/home to websitecom/index, what will happen? I think it will be conflicting. Google will not or cannot index the website.
  
  Am i right?...

  Ryan Cramer: Sounds like a nasty redirect loop.  ;I've seen this happen with internal pages, but for the DefaultRoot?
  
  There is a time where you may want to do something like this, for instance you can have redirects based on language, and want everyone to feel special you can have /home for English, /index for Hindi, and / for Spanish (although I prefer the /en/ /hi/ /es/  ;method).  ;However, if not being handled as a switch with a default, and simply redirecting and checking like:
  THIS WILL LOOP IF LANGUAGE IS NOT DEFINED
  on /home: if $(lang) is not "en" then goto /index
  on /index: if $(lang) is not "hi" then goto /
  on / : if $(lang) is not "es" then goto /home
  
  BETTER WAY:
  on all: switch ($(lang))
   ;  ; case "en": goto "/home"
   ;  ; case "es": goto "/"
   ;  ; case "hi": goto "/index"
   ;  ; default "/"

  Rahul Chauhan: Totally Agree with @Rayan Cramer at persent you are creating redirecting loop and this will not let your website get cached.
