[Reason for session deposit in ASP.NET]ASHX, ASPX null (using Flash uploader)

I am using uploadify to upload files, they automatically post to the handler. I then modify the session with the handler that I had setup as a static property in a common class of the website. I then try to access the same session of the ASPX page, and the value is null. I have a feeling this is because of the cookie, but there needs to be a-to-work around this without exposing the sessioni The d in the URL.

Solutions

I found the Answer:when the handler is being called from FLASH (like SWFUpload or uploadify) it does don't pass the current SessionID to the handler. The handler then creates a NEW session. To fix this, do the following:

$ (Selector). Uploadify ({    ' uploadify.swf ',    ' Upload.ashx? Aspsessid=<%=session.sessionid%> '   });

ADD To:Global.asax:

1 voidApplication_BeginRequest (Objectsender, EventArgs e)2 {3     Try4     {5         stringSession_param_name ="Aspsessid";6         stringSession_cookie_name ="Asp.net_sessionid";7         stringSession_value = Request.form[session_param_name]??Request.querystring[session_param_name];8         if(Session_value! =NULL) {Updatecookie (session_cookie_name, Session_value);}9     }Ten     Catch(Exception) {} One } A  - voidUpdatecookie (stringCookie_name,stringcookie_value) - { theHttpCookie cookie =HttpContext.Current.Request.Cookies.Get (cookie_name); -     if(Cookie = =NULL) -     { -HttpCookie Cookie1 =NewHttpCookie (Cookie_name, cookie_value); + Response.Cookies.Add (cookie1); -     } +     Else A     { atCookies. Value =Cookie_value; - HttpContext.Current.Request.Cookies.Set (cookie); -     } -}
