Hi, 

I would like to stop the rendering of a page after a test. Something like :

in the template

<umbraco:Macro Alias="CheckSecurity" runat="server"></umbraco:Macro>
<umbraco:Macro Alias="RenderPage-Part1" runat="server"></umbraco:Macro>
<umbraco:MAcro Alias="RenderPage-Part2" runat="server"></umbraco:macro>

The idea is that the macro CheckSecurity will make some tests, and stop the rendering if some conditions are false (not allowed alttemplate, for example). Then the two following macros should be executed.

I plan to use something like:

<xsl:if test="my false condition">
    <xsl:value-of select="myLibrary:FlushAndEndResponse()"/>
</xsl:if>

and an xslt extension like :

public static void FlushAndEndResponse()
{
    System.Web.HttpContext.Current.Response.Flush();
    System.Web.HttpContext.Current.Response.End();
}

But I end up with an error 

Thread was being aborted.
  at umbraco.macro.loadMacroXSLT(macro macro, Hashtable attributes, Hashtable pageElements)

  at umbraco.macro.renderMacro(Hashtable attributes, Hashtable pageElements, Int32 pageId)

  at umbraco.presentation.templateControls.Macro.CreateChildControls().

Has anyone done something like this in the past?

I'm still on V4.0.3. 

Thanks
