How do I block specific file types?

Using Web Filter, you can block specific file types. 

1. Go to Apps > Web Filter > Rules.
    
2. Here, you can create rules to block file types by using conditions for "HTTP: Request File Extension" and "HTTP: Response File Extension". 
   • Due to the way information is delivered by a website after it is requested, it is best to create two rules, each rule using one of the two condition types above. 
   • Do not place both conditions in one rule, use separate rules for each condition.
      
3. For Action, choose Block.
