How to find out size of session in ASP.NET from web application?

Hello!

How to find out size of session in ASP.NET from web application?

Thanks

• Hello, if you mean Session Timeout, the default timeout is 20 minutes. Here it is a document that can help you to dectect it http://aspalliance.com/520.

  If you want just make it bigger or check your server default, you can check the file web.config.

• Nope. Not session timeout but session size (in kB for example).

  From GrZeCh

• I think you can find that information by adding Trace="true" to the page directive of a aspx page. Then when the page loads you can see a large number of details regarding the page request, including session information i think.

  You can also enable tracing in your entire application by adding a line to your web.config file. Something like:

  <trace enabled="true" requestLimit="10" pageOutput="true" traceMode="SortByTime" 
   localOnly="true"/>
  

  From Rafe

• If you're trying to get the size of Session during runtime rather than in debug tracing, you might want to try something like this:

  long totalSessionBytes;
  BinaryFormatter b = new BinaryFormatter();
  MemoryStream m;
  foreach(var obj in Session) 
  {
    m = new MemoryStream();
    b.Serialize(m, obj);
    totalSessionBytes += m.Length;
  }
  

  (Inspired by http://www.codeproject.com/KB/session/exploresessionandcache.aspx)

  GrZeCh : Thanks. That was what I needed.

  Oliver : I needed to make the following changes: long totalSessionBytes = 0; since m.Length returns a long. But aside from that it's a nice concise piece of code! The loop can be foreach, as well. ;-)

  ddc0660 : @Oliver Thanks for the feedback. I made the adjustments you suggested. Looks a little nicer now.
