Configure connector with IIS site.
Install url-rewrite module for IIS.
Add inbound rule with following settings-
REuqested URL: Mathces Pattern-
Using: Regular Expressions
Pattern: [a-z]

Action Type: Rewrite
Rewrite URL: /bug/index.cfm{PATH_INFO}

In the webroot of the iis site create a directory named bug and add an index.cfm with code
<cfdump var="#CGI.PATH_INFO#">

now access the following url

CGI.PATH_INFO is empty string

CGI.PATH_INFO should be var12/var34

    I've verified ColdFusion 10 Update 1's isapi_redirect.dll fix works properly and CGI.PATH_INFO correctly returns the {PATH_INFO} from the IIS Rewrite Rule. Very cool!

    Here is a workaround.
    Use URL variables instead.

    Requested URL: Matches the Pattern
    Using: Regular Expressions
    Pattern: ^([^/]+)/([^/]+)
    Action type: Rewrite
    Rewrite URL: /bug/index.cfm?v1={R:1}&v2={R:2}
