 * I’m using a method suggested by Kafkaesqui of determining whether the adress 
   you’re at is *www.mysite.com/index.php* or *www.mysite.com/whatever* — so I can
   alter my homepage without essentially altering the way every other page/post 
   displays by default. This is what I’m using at the moment and it works great:
 * (this code is in my index.php / ‘mainpage template’)
 * <?php if($_SERVER[‘QUERY_STRING’]) : ?>
    //do stuff <?php else : ?> //do different
   stuff <?php endif: ?>
 * But what I want to know is how I can extend this to
 * 1. first check if browser is at index.php, and if so, do //stuff
    2. check if
   browser is at [http://www.mysite.com/](http://www.mysite.com/)**?cat=***anything*,
   and if so, do //otherstuff 3. else do //normalstuff
 * so my guess would be that I should use a *switch/case* type of function instead
   of *if/else*… how can I do this?
 * btw thanks support volunteers, I’ve found answers to about a dozen questions 
   by searching these forums so far 🙂

 * Look in codex for these functions
    is_home() is_category() etc.
 * Although I think the meaning is self-evident 🙂
