=== Shared web hosting and cPanel ===

Perl’s role in shared web hosting is historically significant. For many users in the 1990s and 2000s, shared hosting meant a Unix-like account with FTP access, a `public_html` directory, a `cgi-bin` directory, Apache, email, logs, and a control panel. Perl CGI scripts were one of the standard ways to add dynamic behavior to such accounts.

Users installed guestbooks, form-mail scripts, counters, shopping carts, upload handlers, mailing-list tools, classified-ad scripts, and simple database applications. Many of these were Perl CGI programs copied into `cgi-bin`, edited for local paths, and made executable.

This created both opportunity and trouble. Perl made dynamic web programming widely available, but poorly written CGI scripts also became a common source of security problems. Form-mail scripts were abused for spam. Upload scripts could be misconfigured. File permissions and tainted input mattered. The ease of deploying Perl CGI was powerful, but it required care.

'''cPanel''' is especially relevant to Perl’s shared-hosting history. cPanel & WHM became one of the major commercial control-panel systems for shared hosting providers and resellers. cPanel’s own documentation states that cPanel & WHM’s backend is Perl-based and that Perl can be used in many custom cPanel & WHM applications, including through the LiveAPI Perl module.<ref>cPanel API Documentation, “Guide to Perl,” https://api.docs.cpanel.net/guides/guide-to-perl, accessed July 3, 2026.</ref>

cPanel documentation also provides current Perl environment information for supported operating systems and notes that Perl modules can be managed using the `cpan` command or WHM’s module installer interface.<ref>cPanel API Documentation, “Guide to Perl in cPanel - Perl Environments,” https://api.docs.cpanel.net/guides/guide-to-perl/guide-to-perl-in-cpanel-perl-environments, accessed July 3, 2026.</ref>

cPanel also maintains documentation for troubleshooting Perl and CGI scripts, showing that Perl CGI remains part of the operational reality of hosted web environments even after Perl’s decline as the default language for new small websites.<ref>cPanel Documentation, “Troubleshooting Guide for Perl and CGI Scripts,” https://docs.cpanel.net/knowledge-base/scripts-and-utilities/troubleshooting-guide-for-perl-and-cgi-scripts/, accessed July 3, 2026.</ref>

This is an important historical irony. PHP became the more visible shared-hosting application language, but Perl remained deeply present in the hosting infrastructure itself. Control panels, installers, maintenance scripts, account tools, mail-processing scripts, log processors, and administrative automation often relied on Perl.
