Hello!
There are two site: site A is DNN (v 7.1.2) and site B isn't DNN
I have to configure some URL rewrite rules for "hiding" CROSS DOMAIN requests from A to B. So I want:
when request http://A/customscript -> rewrite to http://B/customscript
I've configured on IIS: enabled Proxy in Application Reqeust Routing (ARR) extension and added rules for site A in IIS URL rewrite module:

<rewrite>

            <rules>

                <clear />

                <rule name="rewrite customscript" stopProcessing="true">

                    <match url="^customscript" />

                    <action type="Rewrite" url="http://B/customscript" appendQueryString="false" />

                </rule>

            </rules>

        </rewrite>

When "humanfriendly" mode is enabled in web.config for DNN all works fine as expected. I've seen URL http://A/customescript but executes http://B/customscript
Dnn web config:
<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="[^a-zA-Z0-9 _-]" urlFormat="HumanFriendly"/>

BUT when I switch to "advanced": I've got 404 from A-site. Looks like DNNFriendlyUrlProvider intercepts what was done by IIS URL Rewrite (I checked IIS failed request log and saw that IIS URL rewrite module done his job correctly)
<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="[^a-zA-Z0-9 _-]" urlFormat="advanced"/>

How can I fix it? I want use "advanced" mode together with IIS URL rewrite module
