I’m converting a site from static HTML to dynamic ASP.Net but I don’t want to rename every page or worry about dropping in pages in the search engines. So I decided to just map HTML files to the ASP.Net processor. I could have sworn that I had done this before and all I had to do was make the normal IIS setting change (http://msdn.microsoft.com/en-us/library/bb515343.aspx). But that just returned a blank page. The fix is to add a buildProvider and an httpHandler.
<configuration> <system.web> <compilation debug="false"> <buildProviders> <add extension=".html" type="System.Web.Compilation.PageBuildProvider"/> </buildProviders> </compilation> <httpHandlers> <add verb="*" path="*.html" validate="false" type="System.Web.UI.PageHandlerFactory" /> </httpHandlers> </system.web> </configuration>
