Question

What is the best solution to URL Rewriting in .NET 4. I’m looking for an easy solution to rewrite URLs like

“myurl.com/ApplicationName/Kohls” to something like “myurl.com/ApplicationName/index.html?store=Kohls” so I can access the var “Kohls” through the Query String.

I am currently using the Global.asax and it has been working for the above case – but I am running into trouble in the case where the user would enter myurl.com/Application, with no “/” or anything after Application.

I currently have this:

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        String CurrentURLPath = Request.Path.ToUpper();

        Match nothingAfterRoot = Regex.Match(CurrentURLPath, @"/ApplicationName(/)?$", RegexOptions.IgnoreCase);
        if (nothingAfterRoot.Success)
        {
            HttpContext myContext = HttpContext.Current;
            myContext.RewritePath("/ApplicationName/Default.aspx?store=ABC");
        }
        else
        {
            Match match = Regex.Match(CurrentURLPath, @"/ApplicationName(/)?(\w)*$", RegexOptions.IgnoreCase);
            if (match.Success)
            {
                CurrentURLPath = CurrentURLPath.Trim('/');
                String store= CurrentURLPath.Split("ApplicationName/".ToCharArray())[1];
                HttpContext myContext = HttpContext.Current;
                myContext.RewritePath(String.Format("/ApplicationName/Default.aspx?store={0}", store));
            }
        }
    }

Use MVC framework if you have the option. The URL rewriting is the default.

For traditional asp.net sites, I use the UrlRewritingNet.UrlRewriter.dll with the following to my web.config file:

<configSections>
    <section name="urlrewritingnet" restartOnExternalChanges="true" 
        requirePermission="false" type="UrlRewritingNet.Configuration.UrlRewriteSection, 
        UrlRewritingNet.UrlRewriter" />
</configSections>

<system.web>
    <urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" 
         defaultPage="default.aspx" defaultProvider="RegEx"       
         xmlns="http://www.urlrewriting.net/schemas/config/2006/07">
        <rewrites>
          <add name="ArticleUrlRewrite" virtualUrl="^~/a-(.*)-([\w-]*)\.aspx" 
               rewriteUrlParameter="ExcludeFromClientQueryString" 
               destinationUrl="~/article.aspx?id=$1" ignoreCase="true" />
        </rewrites>
    </urlrewritingnet>
</system.web>
