  HI.
  
  I have been using the radcompression to compress viewstate for a while on an intranet based app. As the number of users has grown quite significantly the use of  RadSessionPageStateCompression is now causing problems - IIS seems to be recycling the app pool A LOT.
  
  I looked at using instead but this actually increases the size of the page in our test environment (IIS 6 running without IIS compression). I have not tried it on the live system which is IIS7 WITH IIS inbuild compression turned on for dynamic pages.
  
  if i remove the browser file the page is 127k, with RadHiddenFieldPageStateCompression it is 138k!
  
  
  can someone please advise if this is an issue with the adapter?
  
  ALso if anyone has any good suggestions on how to use Telerik.Web.UI.RadSessionPageStateCompression, but is able to handle 100ish concurrent users without causing teh app pool to reclycle frequently that would be very helpful too.
  
  thanks
  
  james

  Hello James,
  

  Please try enabling the RadCompression using the following help topic and remove the browser file settings you have previously set.
  Let me know if this makes any difference.

  we are using the browser file to enable viewstate compression, which greatly reduces the size of the page. we wouldnt want to get rid of that functionality.
  
  Can the viewstate compression be turned on without the broser file?

  Hi James,
  
  

  By enabling the compression using the previously provided help topic the viewstate compression will be correctly enabled. Please gives this suggestion a try and let me know if it works.

  
  All the best,

  Sorry if i'm missing something, but the only mention of how to enable viewstate compression in the link is to use the browser file, but you are telling me to remove the browser file.
  
  I am a bit confused.

  Hi James,
  
  Excuse my previous misunderstanding.
  
  The answer I has provided was regards to enable simple RadCompression without such for the ViewState.
  In your case you could try enable the compression for particular pages using the RadCompressionSettings attribute on the page in question:
  C#
  

  [RadCompressionSettings(HttpCompression = CompressionType.ViewState)]  

  public partial class _Default : System.Web.UI.Page  

  {  

     ...  

  }

  
  
  
  
  
  Best wishes,

  Hello,
  
  I have the same prioblem, could you make clear if with .net 4 and last Telerik version we DO NOT have to use the .browser file and the control adapter to have our viewwstate compressed, we simply have to set an attribute to the Page class
  [RadCompressionSettings(HttpCompression = CompressionType.ViewState)] 
  
  
  How to trace server side that the wiewstate is compressed on each call, ajax or not ?
  
  Thanks

  download fiddler2 - it allows yo uto see the actual size of the pages as they are downloaded.
  
  turn the compression off to see the normal size, then compare it after turning compression on.
