 *
 *  file:  tpb-rss.php
 *
 *  Basic Instructions:
 *  Please customize the SECRET_KEY below.
 *
 *  Hit this page passing two GET variables, key and:
 *
 *    category 
 *      or
 *    user
 *      or
 *    search [plus categories optional] 
 *
 *  where key is the SECRET_KEY specified below and:
 *
 *    category is the category # from The Pirate Bay
 *
 *    or user is the user name from The Pirate Bay
 *
 *    or search is the search term and searchCats is an optional list
 *      of comma separated categories from The Pirate Bay 
 *
 *  Example: 
 *  For the Audio > Music category, I would use  tpb-rss.php?key=MySecretCode&category=101
 *  For TvTeam uploads, I would use tpb-rss.php?key=MySecretCode&user=TvTeam
 *  For searching for Dexter, I would use tpb-rss.php?key=MySecretCode&search=Dexter
 *
 *  CACHE INFO:
 *  
 *  The cache feature is to lessen load both on your server, but more importantly
 *  The Pirate Bay. Some clients may update RSS very frequently, and this feature is 
 *  designed to lighten that load.
 *
 *  In order for the cache to work, the CACHE_PATH must exist and the apache process
 *  must have read/write permission to it.
 *
 *  CACHE_TIME is set in minutes, and should be higher than 60 minutes to be useful. The 
 *  default is 120 minutes.
 *  
 *  The cache setting can be overridden via the GET variable bypass_cache
 *  Set it to 1 in order to bypass the cache.
 *
 *  Example: 
 *    tpb-rss.php?key=MySecretCode&category=101&bypass_cache=1
 *  
 *  OPTIONAL PARAMETERS / EXTENDED FEATURES:
 *  
 *    TRUST FILTERS
 *    
 *    You can filter results based on VIP and/or TRUSTED status. To do so, add the following
 *    parameter to the URI:
 *  
 *    Filter based on VIP only: 		TrustedVIP=1
 *    Filter based on TRUSTED only: 		TrustedVIP=2 
 *    Filter based on TRUSTED or VIP only: 	TrustedVIP=3
 *  	
 *    EXTENDED RESULTS
 *    
 *    Extended results combines multiple pages of results into one RSS feed. This is AWESOME
 *    because the odds of missing a torrent is greatly lessened. 
 *    This feature is great when used in combination with the cache feature, as it puts a lot less
 *    load on your server as well as thepiratebay.
 *    If you use this feature and use caching, I recommend increasing the cache time by 20-30 minutes 
 *    per page.
 *    
 *    To use this feature, add the following parameter to the URI:
 *    
 *    pages=# 
 *    
 *    where # is the number of pages to request (maximum of 10)
 *    
 *    The 10 page limit is hardcoded, but can be changed if you desire. I don't recommend increasing this value
 *    as you will unlikely gain much from anything higher. Also, in my testing, 10 pages of results takes about 
 *    15 seconds to render. Increasing this higher will begin to create timeouts. Diminishing returns, people. 
 *    
 *
