Process to connect client to server via proxy for cephalometric analysis program

Internet connection between client and server for running the web applications and processing the data between clients and servers can be done without passing through the proxy. However, the security issues and the access restriction by the institutes which handle the internet access on the client side has compelled the user to make a connection to the server via the proxy. This paper will show how to make a connection via proxy by applying Indy components for C++ Builder to enable the connection between client and server using the log in, user password, and proxy address and proxy port number from the registry to along with setting the maximum connect time and maximum red time to initialize a connection via a proxy before sending the encoded data for the identification of the user to the server. After that, Indy components will check if the connection has become successful. If the connect has become successful, disconnect and clear input buffer of the Indy component and perform decoding and reading the data returned from the server to see whether the server will give the permission to run the program. The results show that this can be done with success.
