Both require careful examination of existing code because you can no longer assume in your CGIs that all resources will be automatically freed by the operating system after the request is served. 0 that embeds a Perl interpreter inside the Apache web server. In addition to a powerful API to Apache internals, mod_perl includes a CGI compatibility mode that provides an environment that allows existing Perl CGIs to run with little or no modification. Since the scripts are run inside a persistent, in-process interpreter, there is no startup penalty.
It may be that the server is not running at all. Then ensure that you can connect to Apache from the local machine. To do this, use telnet to connect directly to the server and issue a sample request. Next, ensure that Apache running on the correct address/port combination. If you can access the server locally, but not remotely, Apache is likely listening on a local address or port that is not accessible remotely. Use netstat or lsof to determine on which addresses Apache is listening and ensure that they are correct.
If you are running Apache on a nonstandard port, you may be blocked. How to fix this varies from distribution to distribution. For example, you can use the system-config-securitylevel tool on Fedora systems and the Windows Firewall tool in the Windows Control Panel. Finally, if you are using Secure Sockets Layer (SSL) to access the server (explained in Chapter 7) and you are connecting using older browser versions or running unusual configurations, check the error log for problems related to SSL data encryption.
