I'm trying to use the 3.6 method of extension mapping and can't get it working. There are a few things that are unclear in the KB article that might be the problem.

From the article:

Note: The defaultExtension attribute's value must be set to the old extension from the urlRewriteFormat attribute (see step 2).

Are you saying that an Image Library should always have a default extension of ".sflb.ashx"?

Step 4 talks about a "Configuring IIS" section in the User Manual. I don't see a section like that.

The IIS mapping part sounds like my problem. I'm on IIS 5.1 (XP Pro). The preview page in the Image Library uses the jpg file instead of sflb.ashx. But the preview page can't display it because pulling up the jpg causes a 404.

Thanks,
Jeff

Hi Jeff,

As I see it step 3 refers to the defaultExtension. There you need to set the default extension for the Libraries provider - sflb.asxh, since you will have {Extension} for the provider ( as described in step 2);

As for the step 4 - you need to add handler mappings under IIS for jpg and other extensions ( say png, gif etc).

   1. From the Start menu, right-click Computer, then click Manage.
   2. Expand Services and Applications, Internet Information Services.
   3. Right-click Web Sites and select Properties.
   4. On the Home Directory tab, click Configuration.
   5. Map the file extension
         1. Click Add.

         2. In the Add/Edit Application Extension Mapping dialog box, click Browse.

         3. Browse to the folder that contains the aspnet_isapi.dll, select the file, then click Open.

         4. Specify .jpg as the extension.

         5. Make sure Check that file exists is unchecked.

         6. Click OK, and OK again to return to the Web Sites Properties dialog box.

   6. Click OK to close the dialog box.

I hope this helps.

Thanks Ivan. Adding the extension to IIS did the trick.

It would help others out if you added these steps to the KB article.

I am trying to get the real file extensions working as well, but I am not having much luck. I have followed the original KB article as well as this post and I am still not able to see any of the images I upload to the images and documents module.

Any help would be greatly appreciated as I am evaluating this product (version 3.7).

I should note that I am running IIS 6 on Windows XP.

Hi Brian,

There should not be a problem with the KB. It works correctly. Make sure that you have followed all steps correctly. Try to remove the images from the module and upload them - or do it only for a single library. There is also another KB that explains different way to get real extensions - How to filter the default ContentHttpHandler by extension

Kind regards,

Ivan,

I've been working on this issue for nearly two days. I've read and re-read the KB article. I've added the mappings to IIS, restarted IIS, removed all of the images from the library I created and re-uploaded them. The only difference I am seeing is the extension of the file I've uploaded (instead of .sflb.ashx it's showing .jpg). I still get the 404 error when attempting to view the original and I'm also receiving the red x in place of the image in the image library.

Any other thoughts?

Below are the changes I made to the web.config (corresponding to the steps in the KB). Perhaps you will see something.

STEP 1: Modules

    <modules>
      <remove name="ScriptModule" />
      <remove name="Cms" />
      <remove name="LibraryModule"/>
      <remove name="RadUploadModule" />
      <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      <add name="Cms" type="Telerik.Cms.Web.CmsHttpModule, Telerik.Cms" />
      
      <add name="LibraryModule" type="Telerik.Libraries.LibraryHttpModule, Telerik.Libraries"/>
      <add name="RadUploadModule" preCondition="managedHandler" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />
    </modules>

STEP 1: httpModules

    <httpModules>
      <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      <add name="Cms" type="Telerik.Cms.Web.CmsHttpModule, Telerik.Cms" />
      
      <add name="LibraryModule" type="Telerik.Libraries.LibraryHttpModule, Telerik.Libraries"/>
      <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />
    </httpModules>

STEP 2:

    <cmsEngine defaultProvider="Generic_Content">
      <providers>
        <clear />
        <add name="Generic_Content" urlRewriteFormat="[Publication_Date]/[Name].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="True" defaultMetaField="Name" securityProviderName="" allowLocalization="False" allowVersioning="True" allowWorkflow="False" allowComments="false" commentsModeration="true" versioningProviderName="" connectionStringName="GenericContentConnection" type="Telerik.Cms.Engine.Data.Providers.DefaultProvider, Telerik.Cms.Engine.Data" />
        <add name="News" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Title" securityProviderName="" allowVersioning="True" applicationName="/News" versioningProviderName="" commentsModeration="true" connectionStringName="GenericContentConnection" type="Telerik.News.Data.DefaultNewsProvider, Telerik.News.Data" />
        <add name="Blogs" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Title" applicationName="/Blogs" allowVersioning="True" allowComments="true" commentsModeration="false" allowLocalization="False" localizationProviderName="" allowWorkflow="False" securityProviderName="" versioningProviderName="" connectionStringName="GenericContentConnection" type="Telerik.Blogs.Data.DefaultBlogProvider, Telerik.Blogs.Data" />

        <add name="Libraries" urlRewriteFormat="~/{Provider}/{LibraryName}/[Name]{Extension}" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Name" applicationName="/Libraries" allowVersioning="False" allowLocalization="False" localizationProviderName="" allowWorkflow="False" securityProviderName="" versioningProviderName="" connectionStringName="GenericContentConnection" type="Telerik.Libraries.Data.DefaultProvider, Telerik.Libraries.Data" tagEditorTemplate="~/Sitefinity/Admin/ControlTemplates/Libraries/BatchTagsEditor.ascx" />
        
        
        
        
        <add name="Events" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Title" securityProviderName="" allowVersioning="True" applicationName="/Events" versioningProviderName="" commentsModeration="true" connectionStringName="GenericContentConnection" type="Telerik.Events.Data.DefaultEventsProvider, Telerik.Events.Data" />
        <add name="Wiki" urlRewriteFormat="[Wiki]/[Name].aspx" urlWhitespaceChar="_" visible="False" defaultMetaField="Name" securityProviderName="" allowVersioning="True" applicationName="/Wiki" versioningProviderName="" allowComments="true" commentsModeration="true" connectionStringName="GenericContentConnection" dataFile="~/App_Data/Wikis.xml" type="Telerik.Wiki.Data.XmlProvider, Telerik.Wiki.Data" />
      </providers>

STEP 3:

      <extensionMapping defaultExtension=".sflb.ashx">
        <add key=".jpg"/>
        <add key=".gif"/>
        <add key=".doc"/>
<add key=".pdf"/>
<add key=".csv"/>
<add key=".xls"/>
      </extensionMapping>

Hello Brian,

Make sure that you have added the handler mappings. Try adding Wildcard ScriptMap as well. The only reason for getting 404 is when the request is not processed by the handler.

Is there a way to "automagically" update all your old URLs to use the proper file extension? I've just upgraded to 3.7 SP3 from 3.2 SP1 and all new links work perfectly, but the old ones still point to .sflb.

Hello Jason M,

You could use ReplaceTool - Globally replace everything in your project with zero efforts
or create a custom tool that will replace the old links in your content.

All the best,
