....Cached dynamic pages can be served from our system at roughly the same rates as static pages. In order to achieve these rates, the Common Gateway Interface (CGI) 15] for invoking server programs cannot be used because it incurs too much overhead. Instead, an interface such as FastCGI [14] NSAPI [13], ISAPI [11] or ICAPI (by IBM) should be used. Our system used the FastCGI interface for invoking server programs. When a request for a dynamic page is received, the server program invoked to satisfy the request first determines if the page is cached. If so, the cached page is returned. ....

....by linking server programs directly with the Web server, preforking multiple processes or threads which the Web server communicates with to invoke server programs, and the use of multithreaded Web servers. FastCGI [10] by Open Market uses the first approach while the Netscape Server API (NSAPI) [8] and ISAPI by Microsoft use the second approach. Over time, more servers will support API s such as Fast CGI, NSAPI, and ISAPI, so the overhead of invoking server programs will drop substantially. If the cost of invoking server programs is not high, dynamic argument embedding will not ....

.... An optimization which would improve performance considerably for small documents would be to maintain long running processes with persistent open connections to the database [8] At this point, it might be possible to further improve performance by using faster interfaces than CGI such as NSAPI [10], ISAPI [9] ICAPI by IBM, or FastCGI [11] Performing the latter optimization without the former would result in little performance improvement because the overhead for connecting to DB2 is considerably higher than the overhead for invoking programs via CGI.

The function is implemented as a CGI program [6] It could also be implemented using proprietary interfaces for invoking server programs such as NSAPI [9], ISAPI [3] ICAPI by IBM, and FastCGI [11] which are generally faster than CGI but not as standard. Similarly, the coordinator has a CGI program display coordinator home page which is invoked when a client follows a hypertext link on a store to the coordinator.
