I was following this tutorial for caching by query:

http://www.theoutfield.net/blog/2011/02/caching-an-umbraco-macro-by-querystring-parameter

When I access my page like this: /theme?entityId=1&themeId=2

This gets cached by query & page and everything works fine.

The problem is with url rewriting as these url's are accessed in another way like this:

    <add name="entityTheme" 
         virtualUrl="~/(.*)/(\d*)/thema/(\d*)/(.*)" 
         rewriteUrlParameter="IncludeQueryStringForRewrite" 
         destinationUrl="~/$1/theme?entityId=$2&amp;themeId=$3"
         ignoreCase="true" />

With macro:

<umbraco:macro runat="server" Alias="Theme" PageId="[@entityId],[@themeId]" />

Without caching I get the specific content based on the query, but when I cache it it gets the content from the first page and it gets cached and every other page displays this cached one.

It's as if the code recognizes the id via:

Request.QueryString["entityId"]

But the macro not via this:

<umbraco:macro runat="server" Alias="Theme" PageId="[@entityId],[@themeId]" />

I didn't found any information or bugs around this so I like to be confirmed if this is a bug or am I forgetting something with the url rewriting?

BTW I'm using Umbraco 4.7.2
