4. IIS Request Processing
Server functionality is
split into ~ 40
modules...
Modules plug into a
generic request pipeline…
Modules extend
server functionality
through a public
moduleAPI.
Send Response
Log Compress
NTLM Basic
Determine
Handler
CGI
Static
File
ISAPI
Authentication
Anon
SendResponse
Authentication
Authorization
ResolveCache
ExecuteHandler
UpdateCache…
…
…
ASP.NET
PHP
Monolithic implementation
Install all or nothing…
Extend server functionality
only through ISAPI…

5. IIS 6.0 ASP.NET Processing
Runtime limitations
Only sees ASP.NET requests
Feature duplication

6. IIS6 Application Framework
support
 Common Gateway Interface (CGI) for
CGI and PHP applications
 Benefits
 Very simple to implement and use – single-threaded execution
 Disadvantages
 Poor performance due to high process creation cost
 Creates and passes request data to a new CGI process
 Waits for CGI process to produce response
 Shuts down CGI process

7. IIS6 Application Framework
support
 Internet Server Application Programming Interface
(ISAPI)
 Benefit of ISAPI
 Can be extremely fast when written correctly
 Disadvantage of ISAPI
 Must be thread-safe (many PHP extensions are
not!)
 Requires development in C++

8. PHP Setup
Binaries
• Use zip file with non-thread safe binaries
• OR download PHP installer
Configure
php.ini
• fastcgi.impersonate = 1
• cgi.fix_pathinfo = 1
• open_basedir = “C:inetpubwebsiteFolder”
Configure IIS
• Enable CGI
• Configure FastCGI handler mapping for *.php
• Change FastCGI settings
Test that it
works
• C:phpphp-cgi.exe –info
• http://localhost/phpinfo.php

9. Per-site PHP configuration
Configuring FastCGI process pool
<fastCgi>
<application fullPath="C:PHPphp-cgi.exe" arguments="-d my.website=website1">
<environmentVariables>
<environmentVariable name="PHPRC" value="C:WebSiteswebsite1" />
</environmentVariables>
</application>
</fastCgi>
Combination of fullPath and arguments uniquely
identify FastCGI process pool definition
PHPRC environment variable
contains path to the php.ini file

10. IIS Extensions
 Mod_rewrite support for URL rewriting

11. SQLServer 2008
 Express version with Management Studio
 Free (as in beer) download
 MySQL .NET drivers (data import/export)
 Open source: Microsoft SQLServer Driver for
PHP
