Issue: In IIS10, IIS logs CF requests incorrectly in a specific scenario. The simple solution should be documented.

Steps to Reproduce:

1) In C:\Windows\System32\inetsrv\Config\applicationHost.config, in the '<location path="" overrideMode="Allow"><modules>' section, place IsapiFilterModule after HttpLoggingModule in the list.
2) Make a request for domain.com and see IIS logged cs-uri-stem as "/" (good)
3) Make a request for domain.com/index.cfm and see IIS logged cs-uri-stem as "/jakarta/isapi_redirect.dll" (bad)

Note: Other fields are also logged incorrectly. Just using cs-uri-stem as an example.

This issue affects clean installs of IIS10, since IsapiFilterModule comes after HttpLoggingModule by default in IIS10.

Suggestion: The "Prepare to install ColdFusion" doc should mention the following bullet, under "Installation considerations for Windows"
-----------
- In IIS10's C:\Windows\System32\inetsrv\Config\applicationHost.config, in the '<location path="" overrideMode="Allow"><modules>' section, IsapiFilterModule must be before HttpLoggingModule in the list. Otherwise, IIS may log CF requests incorrectly (ex: a request for domain.com/mypage.cfm may have cs-uri-stem logged as "/jakarta/isapi_redirect.dll" instead of "/mypage.cfm").
