<div class="content"><p>The GetUniqueConfigPath method is received by the server in
an RPC_REQUEST packet. In response, the server returns the deepest hierarchy
path (up to the specified hierarchy path) that contains a unique set of <a href="59774887-09e3-4de5-ad8e-4794f404b123" data-linktype="relative-path">IAppHostElement</a> objects.
For example:</p><p>Assume: At hierarchy path A, a set of IAppHostElement
objects exist. </p><p>Assume: At hierarchy path B (deeper than A), the identical
set of objects exists. </p><p>Given these assumptions, GetUniqueConfigPath( B ) returns
path A. In other words, the method returns the shallowest path that contains
the identical set of IAppHostElement objects as the specified path. </p><dl>
