Thanks for the post. However I came to this page accidentally regarding another problem. As you said earlier in the comment:

As usual, in shared hosting environment you would need to ensure that account that is used to run php-cgi.exe has minimal set of privileges. It is recommended that you turn on fastCGI impersonation for PHP. That way php-cgi processes for each web site will be running in a security context of impersonated user for that site.

I have w2k3 se sp2 x32, FastCGI, PHP 5.2.12 (fastcgi.impersonate = 1). I have a web site with identity, let’s say, webUser. The application pool for this web sites runs under, let’s say, appPoolUser (part of IIS_WPG group). Web site works fine, but the one thing I can’t understand is the following:
1. Worker process (w2wp.exe) starts under appPoolUser as expected.
2. php-cgi.exe start under the same appPoolUser identity (as per TaskManager).

Why php-cgi.exe does not run under webUser? or am I missing something?

This will be fixed in the RTW release of the FastCGI Extension 1.5.

very nice article but with me i had to modify the fcgiext.ini manually (something wrong with the script) anyway my problem is, no matter what i do it always sees the first TYPE only, and cannot see the rest, i tried all types of syntax and yet always see the 1st entry, any idea why?

About a year ago I wrote an article about how to enable per-site PHP configuration on IIS with FastCGI. The instructions in that article required some non-trivial manipulations of IIS and FastCGI configuration settings. At that time it was one of the p…

At last, Ｉ succeeded in Per-site PHP configuration with IIS7 FastCGI
using GUI.

The only thing I can think of is that it may be possible that Zend Framework relies on the REQUEST_URI server variable to contain the original un-rewritten URL. This server variable is not available on IIS 5.1. ISAPI_Rewrite sets another server variable “HTTP_X_REWRITE_URL” that contains the original URL.

Typically, if PHP application relies on REQUEST_URI, then it is fairly easy to fix it for IIS with ISAPI_Rewrite by adding this code:

if (isset($_SERVER[ 'HTTP_X_REWRITE_URL' ]))
$_SERVER[ 'REQUEST_URI' ] = $_SERVER[ 'HTTP_X_REWRITE_URL' ];
