This feature was added to the EPiServer CMS R2 release.</p> <p>EPiServer has added an eventhandler on the EndRequest event for the HttpRequest. The eventhandler will always be triggered in the end of the request. </p> <p>The eventhandler looks like this:</p> <div id="codeSnippetWrapper" style="border-right: silver 1px solid; padding-right: 4px;

In the case of this property having a Null value you will get an Exception on this call. </p> <p>When developing your own HttpModule and you want to make an URL-redirect in that HttpModule, and you are using the Response.Redirect(url) method, the RedirectLocation property will not automatically be set but the StatusCode property will be set to 301 and there by an exception will be thrown. </p> <p>To avoid this, instead of using Response.Redirect all you need to do is to set the Response.StatusCode to 301 and then set the Response.RedirectLocation property to the new URL. <br />The redirection will there by be taken cared of by EPiServer on the EndRequest event.</p> <p>See this example:</p> <div id="codeSnippetWrapper" style="border-right: silver 1px solid;
