Black Listing

• proxy/blacklist.txt contains a list of blcklisted destinations in CIDR format
• If the proxy server recieves a request for one of these IPs, then the credentials of the client are checked before forwarding the request to the destination.

Basic Access Authentication

• The credentials entered by the client are sent to the proxy server in the HTTP request itself in an encoded manner.
• The proxy server decodes these credentials and checks if its is one the admin credentials stored in credentials.txt

Caching

• When a request is made for more than 3 times in 5 minutes then, a dictionary entry is made for the response for that request.
• The last modification timestamp is also stored in the cache dictionary
• While retreiving a response from the dictionary this timestamp is used to check if the entry needs to be updated
