Convert Apache .htaccess to IIS Web.Config

 

A web.config file is the settings and configuration for applications on IIS Server (ex: Azure Paas Websites ). But what if you’re coming from a Linux host – what then?

Well, there are few options:

1) Online Conversion Tool

http://www.htaccesstowebconfig.com/

As always, please verify the converted web.config rules on a development site before introducing them directly into production.

2) IIS Manager

More on IIS Manager .htaccess conversions here: http://blogs.msdn.com/b/azureossds/archive/2015/04/23/converting-apache-htaccess-rules-to-web-config-using-iis-manager-for-azure-and-iis-websites.aspx

3) Manual Conversion

There is a good article on the equivalent components. It can be found here: http://www.iis.net/learn/application-frameworks/install-and-configure-php-applications-on-iis/translate-htaccess-content-to-iis-webconfig
