copied!<p>If I've understood the question.</p> <p><strong>Assumption</strong></p> <p>The full path is a path with in the current application or a child application. It is not a path limited to the parent nor a path into a sibling application. The desired path is relative to the current applications path.</p> <p><strong>Scenario 1</strong></p> <p>A path such as</p> <p>"/someApp/someFolder/someSubFolder/file.ext"</p> <p>should resolve it to:-</p> <p>"~/someFolder/someSubFolder/file.ext"</p> <p>(although the ~/ notation isn't something ASP classic understands).</p> <p><strong>Scenario 2</strong></p> <p>"/someApp/someSubApp/SomeSubFolder/file.ext"</p> <p>you still want:-</p> <p>"~/someFolder/someSubFolder/file.ext"</p> <p><strong>Scenario 3</strong></p> <p>The app is the root application of the site:-</p> <p>"/someFolder/someSubFolder/file.ext"</p> <p>would still become</p> <p>"~/someFolder/someSubFolder.file.ext"</p> <p><strong>Solution</strong></p> <p>The key to solving this is:-</p> <pre><code>Dim sAppMetaPath : sAppMetaPath = Request.ServerVariables("APPL_MD_PATH") </code></pre> <p>For the above set of scenarios this will result in something like:-</p> <ol> <li>"/LM/W3SVC/33230916/Root/someApp"</li> <li>"/LM/W3SVC/33230916/Root/someApp/someSubApp"</li> <li>"/LM/W3SVC/33230916/Root"</li> </ol> <p>Also</p> <pre><code>Dim sInstanceMetaPath: sInstanceMetaPath = Request.ServerVariables("INSTANCE_META_PATH") </code></pre> <p>will in all the scenarios return</p> <p>"/LM/W3SVC/33230916"</p> <p>With some mathematical reduction we can arrive at the function:-</p> <pre><code>Function ToAppRelative(virtualPath) Dim sAppMetaPath : sAppMetaPath = Request.ServerVariables("APPL_MD_PATH") Dim sInstanceMetaPath: sInstanceMetaPath = Request.ServerVariables("INSTANCE_META_PATH") ToAppRelative = "~/" & Mid(virtualPath, Len(sAppMetaPath) - Len(sInstanceMetaPath) - 3) End Function </code></pre>
