From the web servers angle the CGI program is very important. Suppose a request is received from a client, then the corresponding programs called for. Now the web server collects the output gathered by the program. Thereafter the output is augmented by the server with apt headers and sent for the clients. But the working of CGI has some inherent problem. According to the need of the technology, always a fresh copy of program needs to be executed for each and every request of CGI. As a result the work load is bound to mount very fast and the web server gets overwhelmed. Therefore situation demanded for more efficient technologies to handle such difficulties. Now the efficient technologies including mod Perl or PHP can bail one out of such a difficult poison by allowing the script interpreters to get integrated directly with the web servers. Such integration of the script interpreters with the web server is also known as modules. In this way it avoids repeated loading and initializing interpreters of language. But we have to remember one thing about the application of such a developed technology in the CGI program. This technology is only applicable for different languages of high skill that requires interpreters. There is another way to treat this problem of over loading. Such over loading can be easily handled by applying C languages. The C language or languages of similar compilation can help to handle such problems. It is because such languages have higher level of efficiency as they have the ability to terminate the cycle of execution faster than interpreting the language and for doing this less system of overhead operation is required. The main factors that determine the optimal configuration of web application are details of application specifics, amount of traffic and transaction complicity.
