    copied!<p>Here is a good way to get the current directory even when using rewrite. </p> <p>I needed this to cache some resources in localStorage for an offline web app. With asp.net mvc, the page parameters are written as subdirecties under a page which causes the relative paths to change. Therefore, I needed the absolute path as a key for the resource in the localStorage.</p> <p>Anyway, here it is:</p> <pre><code> var applicationRoot = new System.Uri(Request.Url, Href("~")); var rawURl = Request.RawUrl; var rawUrlAbsolute = new System.Uri(serverRoot, rawURl); var relativeToCurrentPath = Href("SOMETHING_DOESNT_MATTER/../"); var clientPathAbsolute = new System.Uri(rawUrlAbsolute, relativeToCurrentPath); var clientPathAbsoulteStr = clientPathAbsolute.AbsoluteUri; </code></pre> <p>This took me many attempts to figure out. Here is an example using my website:</p> <h3>The path without rewriter</h3> <pre><code> // applicationRoot = http://www.toldpro.com/ // rawURl = /Apps/GreekBible/App/A/B/C // rawUrlAbsolute = http://www.toldpro.com/Apps/GreekBible/App/A/B/C // relativeToCurrentPath = ../../../ // clientPathAbsolute = http://www.toldpro.com/Apps/GreekBible/ // clientPathAbsoulteStr = http://www.toldpro.com/Apps/GreekBible/ </code></pre> <h3>The path rewriten to a subdomain</h3> <pre><code> // applicationRoot = http://greekbible.toldpro.com/Apps/GreekBible/ // rawURl = /App/A/B/C // rawUrlAbsolute = http://greekbible.toldpro.com/App/A/B/C // relativeToCurrentPath = ../../../Apps/GreekBible/ // clientPathAbsolute = http://greekbible.toldpro.com/Apps/GreekBible/ // clientPathAbsoulteStr = http://greekbible.toldpro.com/Apps/GreekBible/ </code></pre> <h3>The rewrite rule:</h3> <p>For more information about this, the following is the rewrite rule I used:</p> <pre><code>// Rewrite: // http://greekbible.toldpro.com/App/* (Client) // to // http://www.toldpro.com/Apps/GreekBible/App/* (Actual) &lt;rule name="Subdomain rewriter" stopProcessing="true"&gt; &lt;match url="App/(.*)" /&gt; &lt;conditions&gt; &lt;add input="{HTTP_HOST}" pattern="^www\.toldpro\.com$" negate="true" /&gt; &lt;add input="{HTTP_HOST}" pattern="^greekbible\.toldpro\.com$" /&gt; &lt;/conditions&gt; &lt;action type="Rewrite" url="/Apps/GreekBible{URL}" /&gt; &lt;/rule&gt; </code></pre>
