title: ISAPI_Rewrite3 IIS Module in Azure App Services PaaS
body: <p>we have a legacy ASP.NET website that depends on the module ISAPI_Rewrite3 for URL rewriting. It uses a .htaccess file.</p>
  
  <p>this was a necessity for URL rewriting before IIS7 which now features a built in URL Rewirite engine.</p>
  
  <p>we want to migrate it to Azure PaaS App Services but can App Services cater for 3rd party modules such as this? </p>
  
  <p>any help is most appriciated</p>
