Windows Vista SP1. SP1 is required on Windows Vista. Overview. The Fast. CGI module in IIS enables popular application frameworks that support the Fast. CGI protocol to be hosted on the IIS Web server in a high performance and reliable way. Fast. CGI provides a high- performance alternative to the Common Gateway Interface (CGI), which is a standard way of interfacing external applications with Web servers that has been a part of the supported IIS feature set since the first release.

CGI programs are executable files that are launched by the Web server for each request to process the request and generate dynamic responses that are then sent back to the client. Because many of these frameworks do not support multi- threaded execution, CGI enables them to execute reliably on IIS by executing exactly one request per process. Unfortunately, it provides poor performance due to the high cost of starting and shutting down a process for each request. Fast. CGI addresses the performance issues that are inherent in CGI by providing a mechanism to reuse a single process over and over again for many requests. Additionally, Fast. CGI maintains compatibility with non- thread- safe libraries by providing a pool of reusable processes and ensuring that each process handles only one request at a time. Enable Fast. CGI Support in IISWindows Server 2.

Go to Server Manager - > Roles - > Add Role Services. On the Select Role Services page, select the CGI check box. This enables both the CGI and Fast. CGI services. Windows Vista SP1. Go to Control Panel - > Programs and Features - > Turn Windows features on or off. In the Windows Features dialog box, select the CGI check box. This enables both the CGI and Fast.

CGI services. IMPORTANT: Install the Update for the Fast. CGI Module. The update for the IIS Fast.

CGI module fixes several known compatibility issues with popular PHP applications. Install the update from one of the following locations: Install the Administration Pack for IISNote.

This step is optional. Among other useful features, the Administration Pack for IIS has a convenient user interface for configuring Fast. CGI settings. The Administration Pack can be installed from the following locations: Install and Configure PHPIt is recommended that you use a non- thread safe build of PHP with IIS Fast. CGI. A non- thread safe build of PHP provides significant performance gains over the standard build by not doing any thread- safety checks, which are not necessary, since Fast. CGI ensures a single threaded execution environment. To install PHP: Download the latest non- thread safe zip package with binaries of PHP: http: //www.

Unpack the files to the directory of your choice (e. Rename the php. ini- recommended file to php. Open the php. ini file. Uncomment and modify the settings as follows: Set fastcgi. Fast. CGI under IIS supports the ability to impersonate security tokens of the calling client. This allows IIS to define the security context that the request runs under. Set cgi. fix. Previously, PHP behavior was to set PATH.

For more information about PATH. Setting this value to 1 will cause PHP CGI to fix its paths to conform to the specifications. Set cgi. force. Typically, for PHP 5. X the value would be set as extension. At the server level, double- click Handler Mappings. In the Add Module Mapping dialog box, specify the configuration settings as follows: Request path: *. Module: Fast. Cgi.

Module. Executable: . If everything was setup correctly, you will see the standard PHP information page. To check if the Fast. CGI module is registered, open the IIS configuration file that is located at %windir%\windows\system. Host. config and check that the following line is present in the < global. Modules> section: < add name=.

In particular, it is recommended to: Use one application pool per Web site. Use a dedicated user account as an identity for the application pool. Configure an anonymous user identity to use the application pool identity. Ensure that Fast. CGI impersonation is enabled in the php.

For more details about security isolation in a shared hosting environment, see Ensure Security Isolation for Web Sites. PHP Process Recycling Behavior. Ensure that Fast. CGI always recycles the php- cgi. PHP recycling kicks in. The Fast. CGI process recycling behavior is controlled by the configuration property instance.

Max. Requests. This property specifies how many requests the Fast. CGI process will process before recycling.

PHP also has a similar process recycling functionality that is controlled by the environment variable PHP. By setting instance.

Max. Requests to be less than or equal to PHP. Open IIS Manager. On the server level, double- click Fast. CGI Settings. In the Actions pane, click Edit.. Next to the Environment.

Variables setting, click the Browse (..) button. If these types of applications are to be hosted on the same server, different PHP versions must be enabled and running side- by- side. The IIS Fast. CGI handler fully supports running multiple versions of PHP on the same Web server. For example, assume that on your Web server you plan to support PHP 4.

PHP 5. 2. 1, and PHP 5. To enable that configuration, you must place corresponding PHP binaries in separate folders on the file system (e. C: \php. 44. 8\, C: \php. C: \php. 52. 5nts) and then create Fast. CGI application process pools for each version: C: \> %windir%\system.

Server/fast. CGI /+. To make the recommended changes, locate and open the php. Setting. Descriptionallow. Disable Fast. CGI logging to prevent PHP from sending error information over stderr and generating 5.

This recommendation was discovered and validated by Radney Jasmin with hosting provider Go. Daddy. com who now offers PHP hosting on Windows Server 2. Fast. CGI. Per- site PHP Process Pools. When each Web site has its own application pool, which is a recommended practice on IIS, it is possible to associate a dedicated Fast. CGI process pool with each Web site. A Fast. CGI process pool is uniquely identified by the combination of full. Path and arguments attributes.

If you need to create several Fast. CGI process pools for the same process executable, such as php- cgi.

With php- cgi. exe processes, you can also use the command line switch . You can use this switch to set a PHP setting that makes the arguments string unique. For example, if there are two Web sites .

The setting also enforces that the PHP executable for each process pool can perform file operations only within the root folder of the corresponding Web site. Then website. 1 can have the PHP handler mapping as follows: < system. Server>. < handlers access. Policy=. The PHP documentation provides a detailed description of the PHP startup process.

One of the places where the PHP process searches for the php. PHPRC environment variable. If the PHP process finds a php. PHP process will revert to using the default location of the php. This environment variable can be used to allow hosting customers to use their own versions of php.

For example if there are two Web sites . This configuration also ensures that if a php.

PHPRC environment variable, then PHP will use the default php. Provide URL Rewriting Functionality for PHP Applications. The majority of popular PHP applications rely on the URL rewriting functionality in Web servers to enable user- friendly and search engine- friendly URLs. IIS provide URL rewriting capabilities by using the URL rewrite module. For more information about how to use the URL Rewrite module, see the following articles: For more information regarding hosting PHP applications on IIS refer to the following resources.
