A DSC script for configuring custom URL Rewrite providers in IIS

This creates a VM Scale Set in Azure for the purposes of using IIS with a custom URL Rewrite provider. This template:

• Downloads custom provider assembly from blob storage (in this case, the FileMapProvider from the rewrite extensibility samples)
• Installs the provider assembly into the GAC
• Installs provider into IIS at the server level (can be modified to use a different scope)
• Downloads additional files and configures the provider
• Sets up sample rewrite rule to Default Web Site using the FileMapProvider, documented here.

WIP

• Azure ARM template still in-progress
• Test-Script for rewrite rules in IISInstall.ps1 isn't very good

Notes

This installs the custom provider at the server level - if you want to use it only on a specific web site, add the provider in at that level and modify the paths appropriately. If you change them, remember to update your later paths. If you use it as-is, expect your web.config in the web site to only include the rewrite rules, not the provider declaration (e.g., the <providers> tag shouldn't exist in the Default Web Site's web.config, as it is already available via applicationHost.config for the whole server).
