iiswsgi

The iiswsgi module implements a FastCGI to WSGI gateway that is compatible with IIS's variation of the FastCGI protocol. In particular, it supports using STDIN_FILENO opened twice, once each approximating the recv and send end of a socket as is specified in FastCGI.

Quick Start

Use IIS's AppCmd.exe to install a new FastCGI application. You can find it at %ProgramFiles%\IIS Express\appcmd.exe for WebMatrix/IIS Express or %systemroot%\system32\inetsrv\AppCmd.exe for IIS. Note that you need to replace %SystemDrive%\Python27\Scripts\test.ini with the full path to a Paste Deploy INI configuration file that defines the WSGI app and IISWSGI-Test with the name of your app as IIS will see it:

> appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='%SystemDrive%\Python27\python.exe',arguments='-u %SystemDrive%\Python27\Scripts\iiswsgi-script.py -c %SystemDrive%\Python27\Scripts\test.ini',maxInstances='%NUMBER_OF_PROCESSORS%',monitorChangesTo='%SystemDrive%\Python27\Scripts\test.ini']" /commit:apphost
> appcmd.exe set config -section:system.webServer/handlers /+"[name='IISWSGI-Test',path='iiswsgi-test.fcgi',verb='*',modules='FastCgiModule',scriptProcessor='%SystemDrive%\Python27\python.exe|-u %SystemDrive%\Python27\Scripts\iiswsgi-script.py -c %SystemDrive%\Python27\Scripts\test.ini']" /commit:apphost

See the IIS FastCGI Reference for more details on how to configure IIS for FastCGI.

Sample Package

The sample.msdeploy sub-directory can be used to build a sample MSDeploy package to be used with the web-pi.xml file as a custom Web Platform Installer feed to test or as a basis for building your own packages and custom feeds.

1. Exit the Web Platform Installer

   To make sure it uses the current version of the package and feed.

2. Build the package

   A script is provided to make this easier. Change to the directory containing this file in a cmd.exe prompt and run the following command:

   >C:\Python27\python.exe build_package.py
   

   That will build the package, clear the WebPI caches, and update the custom feed.

3. Point WebPI to the local feed

   Skip this if you've already done it before.

   Force WebPI to use the modified feed. Use the WebPI options screen to remove any previous Plone installer feeds and adding file:///C:/.../iiswsgi/web-pi.xml replacing ... with the appropriate path.

4. Install the package in WebPI

   Use the search box in WebPI to search for iiswsgi, click Add then click the Install button below and follow the instructions.
