Open Proxies
Open Proxies encourages the customers to disguise their IP address while perusing the web.
Turn around Proxies
In this the solicitations are sent to at least one intermediary servers and the reaction from the intermediary server is recovered as though it came straightforwardly from the first Server.
Engineering
The intermediary server engineering is separated into a few modules as appeared in the accompanying graph:
Intermediary UI
This module controls and deals with the UI and gives a simple to utilize graphical interface, window and a menu to the end client. This menu offers the accompanying functionalities:
Begin intermediary
Stop intermediary
Exit
Blocking URL
Blocking customer
Oversee log
Oversee store
Adjust design
Intermediary server audience
It is where new solicitation from the customer program is tuned in. This module additionally performs hindering of customers from the rundown given by the client.
Association Manager
It contains the primary usefulness of the intermediary server. It plays out the accompanying capacities:
It contains the primary usefulness of the intermediary server. It plays out the accompanying capacities:
Peruse demand from header of the customer.
Parse the URL and decide if the URL is blocked or not.
Produce association with the web server.
Peruse the answer from the web server.
On the off chance that no duplicate of page is found in the store, at that point download the page from web server else will check its last changed date from the answer header and in like manner will peruse from the reserve or server from the web.
At that point it will likewise check in the case of storing is permitted or not and as needs be will reserve the page.
Store Manager
This module is in charge of putting away, erasing, clearing and looking of website pages in the reserve.
Log Manager
This module is in charge of review, clearing and refreshing the logs.
Arrangement
This module makes design settings which thus let different modules to perform wanted arrangements, for example, storing.
Firewall and system information sifting.
