HTTP Compression for your ASP.NET AJAX applications

  If we have gzip compression enabled through IIS, will we still want to do this option in addition?
  
• Vlad 17 Dec
  Hi Chameleoki, Here is the result with default IIS7 compression (without our compression module): - traditional ajax: Bytes Received: 3,883 - JSON: Bytes Received: 2,910 - NO COMPRESSION! Vlad PS: Both "Enable Dynamic Content Compression" and "Enable Static Content Compression" are turned on!

  We're using ASP.NET 2.0 / AJAX 1.0, and I'm curious as to why this won't be supported.

  What's the scheduled release date for the next service pack?
• max 18 Dec
  What about the view state? it becomes huge very fast..
  There is a lot of samples on google and it would be nice if you include event this feature..

  Hi Mark, So far we succeeded with web services JSON compression under .NET 2.0 and Microsoft ASP.NET AJAX 1.0 only - I'll post more info for ajax response (if we have any). Hi Tom, The service pack is scheduled for the first week of 2009 however you can contact the support to receive latest unofficial Telerik.Web.UI build. Hi Max, So far we don't have plans related to ViewState handling - you can use the standard approach (for example SessionPageStatePersister similar to my demo).

  I'm wondering why it doesn't work with pagemethods...
• Vlad 19 Dec
  Hi Cedric, Good news - we've managed to add support for PageMethods as well. Vlad

  Hi all,
  I'm happy to announce that Telerik.Web.UI.CompressionModule will support ASP.NET 2.0 and Microsoft ASP.NET AJAX 1.0.

  We are looking for  HTTP Compression  and we find http://www.codeplex.com/MbCompression with
  
  Features:
  1. Minify and compress JavaScript files.
  2. Minify and compress css files.
  3. Compress aspx pages.
  4. Minify and compress WebResource.axd
  5. Combine multiply javascript or css files to save requests
  
  Advantages:
  1. Easy to implement in existing project.
  2. Every feature can be enabled or disables by configuration in Web.Config file.
  3. All external files (js, css) and WebResources are been cached in client & server.
  4. Time in the cache can be controlled in the Web.Config
  5. Specified type of content can be exclude from the compression
  6. Specified aspx files can be exclude from the compression
  7. JavaScript files that 'injected' by third party component (as Telerik controls) can be compressed too.
  8. Frameworks 2.0, 3.0 & 3.5
  9. The System.Web.Handlers.AssemblyResourceLoader that load the WebResources was rewritten to enable compression and better performance, and without
  making HTTP request each time WebResource need to be served.
  
  is telerik HTTP Compression  is better then MB Compression ? can you give test results for example can telerik module compress axd files and viewstates?
• Jason 15 Jan
  Of course, MbCompression  is better.....
  Telerik compression module is still weakless

  Hi Carlos, Straight onto your questions: - Features from 1 to 5 are part of RadScriptManager and RadStyleSheetManager. 1) Simple and standard http module registration - no need to learn custom config tags. 2) You can configure our compression using RadCompressionSettingsAttribute attribute My opinion is that 3) and 4) are mostly browser/server related. 5) Currently not supported. 6) Please check 2) 7) Supported. 8) Same. 9) Please check RadScriptManager. Furthermore you can compress the ViewState using simple .browser file in your App_Browsers folder: <browsers>   <browser refID="Default">     <controlAdapters>       <adapter controlType="System.Web.UI.Page" adapterType="Telerik.Web.UI.RadHiddenFieldPageStateCompression" />     </controlAdapters>   </browser> </browsers> The page state can be compressed using RadHiddenFieldPageStateCompression or RadSessionPageStateCompression. Hi Jason , Can you share what do you mean by "still weakless"?

  Vlad, this simply doesn't work. I'm using the latest build 2008.3.1314.35 12/11/2008 is there a special build I need or ...?

  Hi John,
  The name of the class was changed from CompressionModule to RadCompression for the official release.
  Sorry for the confusion!
  Vlad
• JohnC 26 Jan
  Shouldn't you update the example web.config snippet at the top then? :)
• Vlad 27 Jan
  Done!
• XavierT 04 Feb
  Where can I find documentation on
  
  2) You can configure our compression using RadCompressionSettingsAttribute attribute
  
  
  RadHiddenFieldPageStateCompression or RadSessionPageStateCompression
  
  thanks
• Chetanya 09 Oct
  Does the radcompression reduce the size of the data returned from WebResource.axd? file requests?
  
  Thanks
• Goce 13 Apr
  Where should i put this in web.config
  
  

  <radCompression>   
    <excludeHandlers>
         <!--This will match only the defaultcs.aspx file inside a grid folder in web site’root-->
         <add handlerPath="grid/defaultcs.aspx" matchExact="true"/>
         <!--This will match every defaultvb.aspx file regardless of its location in the web site-->
         <add handlerPath="defaultvb.aspx" matchExact="false"/>  
         <!--This will match the handlers of all pages which reside in the MyFolder sub-folder of the web site-->  
         <add path="MyFolder/" matchExact="false"/>
    </excludeHandlers>
  </radCompression>

  What about in-browser-compression of data before sent to the server?
  I've found something that sounds interesting...AJAX post compression
  Is there something similar?
