title: Are there alternatives to WebMethod in order to bypass postbacks but access Session
body: <p>So i'm trying to improve performance in our ASP.Net Webforms application.</p>
  
  <p>As usual Postbacks do their best to slow down performance. I've come to learn about WebMethod calls which i managed to get working too. However for my particular scenario i need to access the Session, which is obviously not possible in a static method.</p>
  
  <p>So now my idea was writing a HttpModule to solve this. However this seems like quite an effort, so i was wondering if any of you know about an out of the box solution for this task?</p>
  
  <p>Mind you, this is just a question about wether something already exists. Writing the module would be pretty straight forward. I'd just like to avoid reinventing the wheel.</p>
