Use "Session" from page requested by code

[Peter Theill]

Hi,

I'm trying to include the content of a request into an Xml document:

if (System.Web.HttpContext.Current.Session["user_id"] != null) {
XmlDocument d = new XmlDocument();
d.Load(new XmlTextReader("http://localhost/page.aspx"));
}

The requested page (page.aspx) is an XHTML page so I'm able to parse it as a
document. However if I want to use the current session in that request to
'page.aspx' how would I do that?

In "page.aspx" I reference a UserControl having this code line:

string userId = (string)System.Web.HttpContext.Current.Session["user_id"];

It's empty even though I check for it (first linie) just before requesting
the page. Could anyone help?

1) use webclient and pass along the session cookie and creditials to fetch
the page, then load into the xml document.
2) write the session to a global cache, then pass the cache key

public class SessionCache {
public static Hashtable Sessions[] = new Hashtable();
}


if (System.Web.HttpContext.Current.Session["user_id"] != null) {
string key = System.Guid.NewGuid().ToString();
lock(typeof(SessionCache)) {

SessionCache.Sessions.Add(key,System.Web.HttpContext.Current.Session["user_i
d"]) ;
}
XmlDocument d = new XmlDocument();
d.Load(new XmlTextReader("http://localhost/page.aspx?key=" + key));

lock(typeof(SessionCache)) {
SessionCache.Sessions.Remove(key);
}
}

in the calling page

lock(typeof(SessionCache)) {
HttpSessionState session = (HttpSessionState)
SessionCache.Sessions[Request.Form["key"]];
}

Beautiful. Just what I needed. Thanks for the code snippets.
