HttpHandler and Session Issue

N

Nicolas Beunier

Hi!

I am currently working on a Web Application using some HttpHandlers.

As i need to read/update objects stored in session, each Handler
implements the IRequestSessionState interface.

When requesting the webapplication using urls like
http://localhost/<ApplicationName>/... everything works fine.
A new session is created, and reused on every following requests (same
sessionId).

But when i query the same webapplication (from the same local client)
using http://<MyMachineName>/<ApplicationName>/... i get a new session
Id on every request. Impossible to store anything into SessionState...

To point out the problem, i created a simple test webapplication, with
no aspx, and a single HttpHandler with IsReusable returning true.

Note : In the web.config the cookieless sessionState's attribute is
set to false.

Is this some kind of bug, or am i missing something?

Thoughts are most welcome!

Best Regards,
Nicolas

Hello Bruce,

First of all thank you for helping me!

I think i didn't explained my problem clearly, sorry. I'll try to expose
it a different way.

Let's have for instance this test HttpHandler, only returning the
current session id :

<httpHandlers>
<add verb="*" path="*.test"
type="MyHttpHandler.TestHandler,MyHttpHandler" />
</httpHandlers>

public class TestHandler: IHttpHandler, IRequiresSessionState {
public void ProcessRequest(HttpContext context) {
string sessId = context.Session.SessionID;
context.Response.ContentType = "text/xml";
context.Response.Write(<html><body>);
context.Response.Write("Current sessionId : "+sessId);
context.Response.Write("<form action='sample.test'>);
context.Response.Write("<input type='submit' value='submit'/>);
context.Response.Write("</form>);
context.Response.Write("</body></html>");
context.Response.End();
}
public bool IsReusable { get { return true; } }
}


A) In the first scenario, (http://localhost/myApp/sample.test), i get
the same sessId returned every time i submit the form (this is the
normal behavior i guess).

B) In the second scenario (http://myHost/myApp/sample.test), i get a new
sessId returned every time i submit.
It's just like no cookie is received by the client in scenario B...

Thanks again for the help!

Best regards,
Nicolas

Does your machine name have an underscore character in it? There's a known
issue with odd characters in the names of servers, and I believe this is one
of the symptoms.

Hi John,
Yes indeed, the machine name does have underscore in its name.
Thank you very mutch for that info!
I didn't know about this issue.

I'm going to check with IP.

Best regards,
Nicolas
