Thread: Details of CGI

I want some detail information about CGI technology as I just started learning it. So please tell me aspects of CGI and it how it works. Provide me any information related to this. Any help will be appreciated.

CGI shows how to transmit request to HTTP server program and how to recover generated response. CGI can pass parameters to program, so it thinks them to produce data. E.g. parameter string having search terms with search engine. It's running program then returns produced content, as it was file content.

This technology needs new copy of program is launched for every request; it simply overload servers. This resulted in making of other technologies capable. Usually, applications Web utilized CGI which run new process for every request. Programming is occasionally hard as program is run in regular environment blank and should finally return information from earlier queries.
