Page attribute & concurrency
-
Hi, what if I have a Page subclass A.cs with a protected attribute "foo" and I use it in A.aspx.cs ? what if many users request page A ? what value of "foo" will they see ? Class A:
public class A : System.Web.UI.Page { protected string foo; private void Page_Load(object sender, System.EventArgs e) { foo = "hi there " + Request["AUTH_USER"]; } ...Page A:<%@ Page language="c#" Codebehind="A.aspx.cs" AutoEventWireup="false" Inherits="some.A" %> <%=foo%> ...Thanks in advance for your reply -

So it does not do some sort of object pooling ? for every request it creates an object from that class, serve the request, destroy the object ? :wtf: well... ok, thanks! ---------------------- !happy coding!

AFAIK yes, silly isnt it? static instances are persisted on application level, but be aware ASP.NET tends to go into 'sleep' mode and the values get reset. Other option is to use the Session object. You can just save object instances there that will be persisted for the current session of the user, which is porbably what you are looking for :) Eg:
string id = Session["login"] as string;

Err... no. What I want is a method of passing objects between a class and it's subclass in a concurrent-access-safe-manner and only in the scope of a request/response (I need something like java's Request.setAttribute). ViewState is great, but IMHO only for intranet applications. But, if your answer is correct... I've found it. Thanks! ---------------------- !happy coding!

Ok, wise ass, what would you call it? Maybe not techinically correct, but everyone (bar you) seems to understand it as "an instance of a class that is a static member in some class". :doh: xacc-ide 0.0.99-preview7 now with C#, C, C++, IL, XML, Nemerle, IronPython, Perl, Caml, SML, Ruby, Flex, Yacc, Java, Javascript, Lua, Prolog and Boo highlighting support!
