As a result, instead of providing a patchwork of plug-in points, IIS implements all of its own features on top of the public extensibility model. This design is found throughout the platform, from the modular Web server engine itself to the configuration system to the IIS Manager console. Often, the desired Web workload requires additional functionality that may not be part of the built-in IIS feature set.

Or, in some cases, the application may require a customized set of functionality for which the built-in features are not flexible enough. Because all of the IIS features are built on public extensibility APIs, you can replace any of them with a custom implementation that best fits your needs. By using the IIS Manager extensibility, API developers can take advantage of remote management capabilities for their components for free. IIS Manager has built-in remote administration capabilities.

NET provider. Unlike other tools that also support remote administration, the IIS Manager remote administration architecture offers several key advantages. First, it allows users who are not administrators on the server to manage sites and applications over which they have control. To facilitate the remote management scenario, each management feature consists of two parts: the client-side components that provide the UI experience inside IIS Manager, and the server-side component that provides the actual management services.

The server-side service is loaded inside IIS Manager for local management scenarios or inside the Web Management Service in remote management scenarios. In the latter case, IIS Manager handles the required communication between the components in IIS Manager on the client machine and the service running inside WmSvc on the target server machine. Extending the configuration schema can help manage your application. You can automate deployment of the application script to a virtual directory, or configure the role used to authorize users for caption editing, either system wide or for each Web site or application.

Extending the schema involves adding a simple. This involves adding just one line in the applicationHost. There are two builds for each PHP version. The thread-safe version is designed for environments where the Web server core can keep the PHP engine in memory, running multiple treads of execution for different Web requests simultaneously. The architecture of IIS and the FastCGI extension provide an isolation model that keeps requests separate, removing the need for a thread-safe version.

As a result, you will see a performance improvement on IIS when using the NTS version as compared to the tread-safe version. Unlike the standard CGI implementation, FastCGI enables process reuse by maintaining a pool of worker processes, each processing no more than one request at a time, thus resulting in much-improved performance.

FastCGI also benefitted from a community-centric development and testing model. IIS uses a configuration file named web. This file can be placed at any point within an application, and is used to include Web server directives that affect that directory and the ones below it.

Many applications currently distribute the file. You can use the web. The bold remove entry in this example is required. If there is a previous definition for Index. If there isn't a previous one, the remove will be ignored. These rules can be configured manually or by using the IIS Manager. A typical simple rewrite rule, which converts all requests that come in to http.

IIS uses the Request Filtering module to limit browser access to files or directories based upon specified criteria. An example of how to use request filtering to block access to certain types of files, such as include or log files, follows:.

For the older versions of IIS, it is possible to provide similar protections. Skip to main content. Php Performance On Windows 1. CGI vs. FastCGI 7. FastCGI 1.

Clipping is a handy way to collect important slides you want to go back to later. If you have a page with multiple data sources, these data sources may vary in how quickly they are updated, so using output caching might not be the best solution.

However, if a page has lots of dynamic content that is be updated by separate AJAX calls, then some of the scripts being requested by the AJAX calls might be excellent candidates for output caching. If pages requested by AJAX calls have different query parameters, then you can definitely boost your application performance with output caching. If you then add that pages should be cached according to query string parameter or header value, then all PHP pages with the specified query string parameter or header value may be cached again, probably not what you want.

But, if a query string parameter is unique to a given page, then with this configuration you can be sure which pages will be cached.

Hopefully, this will become clearer as I walk you through configuring output caching think of my test script below as a script requested by an AJAX call. Configuring IIS to use output caching is fairly easy — you can either make some minor changes to your applications web.

However, to really understand how output caching works, I found it helpful to run some tests as I made changes to my configuration.

Think of this as a script invoked by an AJAX call. Note : All page load times that I show in this article should be considered as examples only. By default, when you create a cache rule a page is cached when it is requested 2 times within a 10 second time period. These default values can be changed.

After a page is cached, you have three options in determining when a page is expired from the cache:. To create a file change notification cache rule, open or create the web. Make sure you save your web. Note : By default, a page is only cached if it is requested at least 2 times within a 10 second time period. To learn how to change these default values, see the Change When a Page is Cached section below.
