TTCPServer Web con Soporte de PHP
 

Saludos amigos de la comunidad Delphi, les traigo el código de un servidor web hecho en Delphi 2010 que utiliza el componente TTCPServer de la pestaña Internet de la VCL, funciona todo bien, sin embargo, quisiera saber como agregarle soporte para procesar archivos php, tal como apache agrega su Handler, si alguien puede tomar como base el código que comparto aquí y agregarle el parsing de php, se lo agradecería infinitamente:

Por favor ayuda, se que estoy cerca.
