We can use Apache as frontend HTTP server running on port 80, and Domino on port 81, so that users can access both Apache and Domino pages via port 80 only.This is done via the Apache Rewrite Engine, but until now it caused one nasty problem: When doing a submit on a Domino page, then Domino would add the port 81 to the URL, and the user could not access that page, if only port 80 was opened to the internet.I found a solution how to overcome this Domino's problem, by adding Apache Reverse Proxy Engine to the httpd.conf.It's very simple to setup, just add these lines at the end of your Apache's httpd.conf file, and replace the IP: 1.2.3.4 number with your internet server's IP number or domain name.In this Rewrite setup, I made it so that all .php ending URLs are handled by Apache, and all other URLs by Domino. This gives us the possibility to add php5 and sqlite3 code to any Domino site.
