ASP.NET postbacks and URL rewriting
ASP.NET Web Forms extensively use postback mechanism in order to maintain the state of the server-side controls on the web page. This makes it somewhat tricky to perform URL rewriting for ASP.NET pages. When a server side form control is added to the web page, ASP.NET will render the response with HTML <form> tag that contains an action attribute pointing back to the page where the form control is. This means that if URL rewriting was used for that page, the action attribute will point back to the rewritten URL, not to the URL that was requested from the browser. This will cause the browser to show rewritten URL any time a postback occurs.

Wildcard script mapping and IIS 7 integrated pipeline
The big benefit of IIS 7 integrated request processing pipeline is the fact that all the nice and useful ASP.NET features can be used for any type of content on your web site; not just for ASP.NET-specific content. For example, ASP.NET SQL-based membership can be used to protect static files and folders. Also, ASP.NET extensibility API’s, such as IHttpHandler and IHttpModule can be used to add custom modules and handlers that would be executed even for non-ASP.NET content.

ASP.NET Routing, Request Filtering, URL Rewriting
Today I have published two new articles on http://learn.iis.net. The articles are intended to explain the differences between various URL manipulation technologies available in IIS 7.0 and to provide help with choosing of the technology best suited for a particular usage scenario.

Update for IIS 7.0 FastCGI module
IIS team has recently released an update for IIS 7.0 FastCGI module that fixes compatibility problems with several popular PHP applications. In particular, the update changes the behavior of FastCGI module in the following ways:

Ruby on Rails in IIS 7.0 with URL Rewriter
If you ever tried to set up Ruby on Rails (RoR) on IIS 7.0 with FastCGI you have probably noticed that the process is not very straightforward. There are a few workarounds that need to be applied in order for RoR to function correctly. In particular, handling of static files in your web application can be tricky on IIS 7.0. The problem is that RoR uses clean URL’s that look similar to this: http://mysite.com/home/about. In order for RoR to be invoked for this kind of URL’s it is necessary to create a “catch all” handler mapping in IIS (that is a handler mapping with path attribute set to “*“). When you create such a handler mapping it will cause requests for static files to be routed to RoR, which will obviously fail to handle them.

Scripting URL rewrite module configuration
URL rewrite module fully utilizes extensibility of IIS 7.0 configuration system. The rewrite rules are stored in applicationHost.config and web.config files in XML format. This provides a huge benefit of being able to use rich set of IIS 7.0 management tools and API’s for managing and scripting URL rewriter configuration.

IIS.NET uses URL rewrite module
IIS.NET team has been very proactive in helping us out with testing of URL rewrite module. In fact, they even agreed to deploy the latest build of the module on the production server that hosts http://www.iis.net. This kind of real-life deployments really helps us validate the features and functionality of the module. And being able to do this validation so early in release cycle gives us a good opportunity to adjust the feature set, re-consider some of the design decisions, or just find some very good bugs.

Per-site PHP configuration with IIS FastCGI
There have been a few questions on IIS.NET PHP forum regarding enabling per-site PHP configuration. This is a common requirement when running PHP applications in shared hosting environment, because each PHP application may require a different set of PHP settings. Shared hosting providers often want to provide their customers with an option of controlling PHP configuration if necessary.
