Here is a list of features that i have implemented.
  1. 3 layered architecture.
  2. MetaWeBlog implementation (Partial) [Have tested with BlogJet].
  3. Provider based design - Pluggable providers [Includes SqlProvider].
  4. File system based Image gallery.
  5. Guestbook.
  6. Comments.
  7. Complete administration of site.
  8. RSS feeds
  9. Technorati ping.
  10. Caching features for performance.
I would love to hear some feedbacks on the design so that i could better the application in any way possible.

Well everything seemed to work fine on my dev machine but once i put the code in production, my URL rewriting logic failed. I was using Gaidar Magdanurov's UrlRewiting solution. From what i observed the http module was not picking up on the application load. So as a last minute change i used UrlRewritingNet.UrlRewrite. I did not have to change much of the thing for this to work. Its pretty straight forward to setup and use.

First you have to add a config section 


<configSections>
    <section name="urlrewritingnet" requirePermission="false" type="UrlRewritingNet.Configuration.UrlRewriteSection, UrlRewritingNet.UrlRewriter"/>
</configSections>
The next step is to define the http module ( This is where i think my other solution fails)


<httpModules>
    <add name="UrlRewriteModule" type="UrlRewritingNet.Web.UrlRewriteModule, UrlRewritingNet.UrlRewriter"/>
</httpModules>
Now you are ready to write the rules like so.


<urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage="default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07">
    <rewrites>
        <add name="Post" virtualUrl="Post/(\d+)/(.*).aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="ShowBlog.aspx?ID=$1" ignoreCase="true"/>
    </rewrites>
</urlrewritingnet>
Well you would guess that this is all you do and everything works fine. Even i thought so, but when i was testing this, i logged into my site and the URL which i expected to be something like this "http://vinay.qsh.eu/Post/1/something.aspx" had become "http://vinay.qsh.eu/Post/1/something.aspx?ID=1". This broke my page because there are 2 parameters with the same id. It beats me as to why this is being added on login/logout. It is not a postback issue as every other postback is working fine.

How to fix this? This is what i have done.

Add a helper method to check whether if the URL is rewritten one or plain URL


    1 public static bool URLRewritten(string LocalPath)
    2 {
    3     bool ruleFound = false;
    4     foreach (UrlRewritingNet.Configuration.RewriteSettings rewriteSettings in UrlRewritingNet.Web.UrlRewriting.Configuration.Rewrites)
    5     {
    6         UrlRewritingNet.Web.RewriteRule rewrite = null;
    7         string providerName = rewriteSettings.Provider;
    8         if ((string.IsNullOrEmpty(providerName)))
    9         {
   10             rewrite = UrlRewritingNet.Web.UrlRewriting.CreateRewriteRule();
   11         }
   12         else
   13         {
   14             rewrite = UrlRewritingNet.Web.UrlRewriting.CreateRewriteRule(providerName);
   15         }
   16         rewrite.Initialize(rewriteSettings);
   17 
   18 
   19         if ((rewrite.IsRewrite(LocalPath)))
   20         {
   21             ruleFound = true;
   22             break; 
   23         }
   24     }
   25     return ruleFound;
   26 }
Then use this function in the LoggedIn and LoggedOut events to manage the URL


    1 protected void Login_LoggedIn(object sender, EventArgs e)
    2 {
    3     if (Helpers.URLRewritten(Request.Url.LocalPath))
    4     {
    5         if (Request.Url.PathAndQuery.Contains("ReturnUrl"))
    6             Response.Redirect(Request.Params["ReturnUrl"].ToString());
    7         else
    8             Response.Redirect(Request.Url.LocalPath);
    9     }
   10     else
   11     {
   12         if (Request.Url.PathAndQuery.Contains("ReturnUrl"))
   13             Response.Redirect(Request.Params["ReturnUrl"].ToString());
   14         else
   15             Response.Redirect(Request.Url.PathAndQuery);
   16     }
   17 }
   18 
   19 protected void LoginStatus1_LoggedOut(object sender, EventArgs e)
   20 {
   21     if (Helpers.URLRewritten(Request.Url.LocalPath))
   22     {
   23         Response.Redirect(Request.Url.LocalPath);
   24     }
   25     else
   26     {
   27         Response.Redirect(Request.Url.PathAndQuery);
   28     }
   29 }
One more thing. To manage the Return URL, you'll have to call the helper function like so


    1 if (Helpers.URLRewritten(Request.Url.LocalPath))
    2 {
    3     Response.Redirect(FormsAuthentication.LoginUrl +
    4                   "?ReturnUrl=" + Request.Url.LocalPath);
    5 }
    6 else
    7 {
    8     Response.Redirect(FormsAuthentication.LoginUrl +
    9                    "?ReturnUrl=" + Request.Url.PathAndQuery);
   10 }
I will be using this workaround until i find a fix.
