Understanding Sites, Applications, and Virtual Directories on IIS 7
Mar 17, · The web application needs to be deployed so that it can be accessed by other users. The deployment is done to an IIS Web server. There are various ways to deploy a web application. Let's look at the first method which is the File copy. We use the web application created in the earlier sections. Let's follow the below-mentioned steps to achieve. For IIS to host PHP applications, you must add a handler mapping that tells IIS to pass all PHP-specific requests to the PHP application framework by using the FastCGI protocol. Configure IIS to handle PHP requests by using IIS Manager.
SP1 is required on Windows Vista. FastCGI provides a high-performance alternative to the Common Gateway Interface CGIwhich 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 how to apply emla cream before blood test the high cost of starting and shutting down a process for each request.
FastCGI 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, FastCGI 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.
Install the update from one of the following locations:. The Administration Pack can be installed from the following locations:. 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 FastCGI ensures a single threaded execution environment. Unpack the files to the directory of your choice e. Rename the php.
Set fastcgi. This allows IIS to define the security context that the request runs under. Set cgi. Typically, for PHP 5.
If PHP installed correctly and all its dependencies are available on the machine, this command will output the current PHP configuration information. In the Actions pane, click Add Module Mapping. In the Add Module Mapping dialog box, specify the configuration settings as follows:. Test that the handler mapping works correctly by creating a phpinfo. If everything was setup correctly, you will see the standard PHP information page. If you do not see FastCgiModule in the Modules: list, the module is either not registered or not enabled.
Alternatively, you can complete the steps above by using the command line tool A ppCmd. This download contains a summary what happens if you stop taking depakote on Best Practices for hosting PHP in a shared hosting environment. The recommendation for isolating PHP Web sites in a shared hosting environment is consistent with all general security isolation recommendations for IIS.
In particular, it is recommended to:. For more details about security isolation in a shared hosting environment, see Ensure Security Isolation for Web Sites. Ensure that FastCGI always recycles the php-cgi. This property specifies how many requests the FastCGI process will process before recycling. Open IIS Manager. Select the FastCGI application that you want to configure.
In the Actions pane, click Edit. Next to the EnvironmentVariables setting, click the Browse If these types of applications are to be hosted on the same server, different PHP versions must be enabled and running side-by-side. For example, assume that on your Web server you plan to support PHP 4. To enable that configuration, you must place corresponding PHP binaries in separate folders on the file system e. If you have three Web sites site1, site2, site3 and each site must use a different PHP version, you can now define handler mappings on each of those sites to reference a corresponding FastCGI application how did the industrial revolution spread to america pool.
Each FastCGI process pool is uniquely identified by a combination of fullPath and arguments properties. The following settings can be used to tighten the security of a PHP installation. To make the recommended changes, locate and open the php. This section describes the recommended way of enabling per-site PHP configuration.
This recommendation was discovered and validated by Radney Jasmin with hosting provider GoDaddy. When each Web site has its own application pool, which is a recommended practice on How to host application in iis7, it is possible to associate a dedicated FastCGI process pool with each Web site. A FastCGI process pool is uniquely identified by the combination of fullPath and arguments attributes. If you need to create several FastCGI process pools for the same process executable, such as php-cgi.
With php-cgi. You can use this switch to set a PHP setting that makes the arguments string how to host application in iis7. For example, if there are two Web sites "website1" and "website2" that must have their own set of PHP settings, the FastCGI process pools can be defined as follows:. 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.
When the PHP process starts, it determines the location of the configuration php. One of the places where the PHP process searches for the php. If the PHP process finds a php. This environment variable can be used to allow hosting customers to use their own versions of php.
This way website1 can have its own version of the php. This configuration also ensures that if a php. Microsoft URL Rewrite Module configuration reference Explains the functionality of the module and provides descriptions of all the configuration options. Skip to main content.

Note If you are using PHP version 4. X, you can use php. Is this page helpful? Yes No. Any additional feedback? Skip Submit. Disable remote URLs for file handling functions, which may cause code injection vulnerabilities.
Enable FastCGI Support in IIS
Mar 10, · In general hosting part of the application is not done by developer however in some scenario where the team size is small or we need to host the application on the local server, we developer does all the work. In this article, I am going to show how to host an facetimepc.co application on IIS in Windows 7 Home Premium Operating System/5(7). There are a couple of things that you could check: Check under which application pool the application runs, and check that the application pool uses the integrated pipeline instead of classic.; Check that the facetimepc.co file contains element. This is the place where the HttpModules are registered if you are using the integrated pipeline. Apr 28, · Open the IIS, add a new Application Pool, then choose No Managed Code facetimepc.co Framework version field and finally, select Integrated for Managed pipeline mode field. Step 8 Add a new folder to host your application on IIS and create a virtual directory for it. Don’t forget to choose the Application Pool that you’ve created in Step 7.
In IIS, you can create sites, applications, and virtual directories to share information with users over the Internet, an intranet, or an extranet. Although these concepts existed in earlier versions of IIS, several changes in IIS 7 and above affect the definition and functionality of these concepts. Most importantly, sites, applications, and virtual directories now work together in a hierarchical relationship as the basic building blocks for hosting online content and providing online services.
This article provides a quick overview of applications in IIS 6. In IIS 6. Although they were discussed as separate concepts, and they were conceptually different from a functionality standpoint , an application was not a physically separate object from a virtual directory.
The site root is an exception, as it was implicitly treated as an application even if those properties were not set. These technologies provided additional features and processing for applications hosted in IIS 6. The important question for IIS 6. IIS 7 and above formalizes the concepts of sites, applications, and virtual directories. Virtual directories and applications are now separate objects, and they exist in a hierarchical relationship in the IIS configuration schema.
Briefly, a site contains one or more applications, an application contains one or more virtual directories, and a virtual directory maps to a physical directory on a computer. As in IIS 6. However, each site must contain at least one application, which is named the root application.
And each application including the root application must contain at least one virtual directory, which is named the root virtual directory. These objects work together to form the site. An application is an object important to the server at runtime. NET request-processing pipelines have merged in IIS 7 and above so that content can take advantage of functionality previously provided for only managed code applications.
For example, each managed code application runs in an Application Domain AppDomain. An application can have several virtual directories, and each one will be served by the same AppDomain as the application to which they belong. The following sections explain sites, applications, virtual directories, and their related configurations in more detail. A site is a container for applications and virtual directories, and you can access it through one or more unique bindings.
The binding includes two attributes important for communication: the binding protocol and the binding information. The binding protocol defines the protocol over which communication between the server and client occurs.
The binding information defines the information that is used to access the site. A site may contain more than one binding if the site requires different protocols or binding information. In IIS 7 and above, bindings can apply to any protocol. This service retains the familiar IIS 6. This is useful for technologies that provide application-to-application communication in Web Services over standard protocols. This lets applications that use communication protocols take advantage of IIS features, such as process recycling, rapid fail protection, and configuration that were previously only available to HTTP-based applications.
In addition to containing applications which contain virtual directories and specifying bindings, the following configuration settings belong to the site:.
An application is a group of files that delivers content or provides services over protocols, such as HTTP. In IIS 7 and above, each site must have an application which is named the root application, or default application. However, a site can have more than one application. For example, you might have an online commerce Web site that has several applications, such as a shopping cart application that lets users gather items during shopping and a login application that allows users to recall saved payment information when they make a purchase.
In addition to belonging to a site, an application belongs to an application pool, which isolates the application from applications in other application pools on the server. In the case of managed code applications, make sure to associate your application together with an application pool that is running the.
NET Framework version that your application requires. For each site, you specify one or more bindings to communicate with and access content in the site. For an application to communicate by using a protocol that is specified in the parent site's binding, you must enable the protocol. A virtual directory is a directory name also referred to as path that you specify in IIS and map to a physical directory on a local or remote server.
The directory name then becomes part of the application's URL, and users can request the URL from a browser to access content in the physical directory, such as a Web page or a list of additional directories and files.
If you specify a different name for the virtual directory than the physical directory, it is more difficult for users to discover the actual physical file structure on your server because the URL does not map directly to the root of the site. In IIS 7 and above, each application must have a virtual directory, which is named the root virtual directory, and which maps the application to the physical directory that contains the application's content.
However, an application can have more than one virtual directory. For example, you might use a virtual directory when you want your application to include images from another location in the file system, but you do not want to move the image files into the physical directory that is mapped to the application's root virtual directory.
By default, IIS uses configuration from Web. If you do not want to use Web. Optionally, when you need to specify credentials and a method to access the virtual directory, you can specify values for the username , password , and logonMethod attributes. This is what is in the ApplicationHost.
Depending on whether it is in the application or virtual directory section, it is a root application or a root virtual directory. Default elements are special because they enable you to configure default values for attributes instead of having to repeat the same values in each collection. When an attribute is configured at more than one level, the value at the lowest level is used. Additionally, if the same attribute or child element is configured in both a default element and in the object's collection, the value in the collection will be used.
You should now have a better understanding of sites, applications, and virtual directories in IIS 7 and above. Unlike IIS 6. Skip to main content. Contents Exit focus mode. Note The site root is an exception, as it was implicitly treated as an application even if those properties were not set.
