Re: FASTCGI and release 7.1 Zend CE installation instructions

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

Aaron,

A native program (the IBM-supplied programs for Apache) cannot load an 
AIX program (Zend's port of PHP) as a module.  So Zend server cannot run 
as an Apache module in the native HTTP server.

Their old solution to this was to operate in an Apache module of the AIX 
version of Apache.  That worked, but required two copies of Apache 
(native and PASE) with a proxy between them, and this caused a lot of 
problems for folks.

So they changed it. They eliminated the Apache module and the AIX 
version of Apache, and instead they use FastCGI.  FastCGI involves a 
"never-ending" program running in batch that communicates with the 
Apache server via sockets. It's published as an open standard for 
everyone to use.  PHP has supported FastCGI for a long time, so very 
little extra work was required on Zend's part. (IBM had to add FastCGI 
support to their HTTP server, though.)

In fact, you can run the Zend Core PHP with FastCGI support instead of 
the 2nd HTTP server if you want to.  All Zend really did was package it 
nicely and write the installer to make it easy to setup.  (and provide 
support, etc.)

So that's why it needs to exist.

As for the "ugly port on the URL".  The only reason you get that is 
because you've chosen to run your HTTP server on a non-standard port. 
Frankly, that should *only* be done in test scenarios...  it'll 
doubtless cause firewall problems for some customers if you try to do it 
in production.
