Launching an asp.net application

[sebastien]

Hi
I have an asp.net application that use Session variables.
What I want to do is to launch an second instance of this application
by a link inside the first application.
The problem is: when I launch the second application, this second
application override the session variables values of the first
application.
I can run 2 instances of my asp.net application if I open two browsers
and I enter the url of my web application in the address bar. So, it's
possible to have 2 instances of the same web application but how
launch the second one by I link inside the first one.

Thanks

There is only one instance of the application. You are launching two BROWSER
instances. The application resides on the server. What you're describing is
separate Client Sessions.

If you can describe what you're trying to accomplish with this, I think
someone here can give you a workable solution.

you could easily fake two sessions. use a hidden form variable on the
pages and prefix the session values with it.

Session["hiddenformvalue_" + "myUserState"]

So same session but more than one set of variables.

What I trying to do is create an IETM (Interactive Electronic Technical
Manual) web based. I use the session variables to keep the information
about the book, the collection, the chapter etc.
Inside books you have link to another book. This link must be open into
another browser because the user need to have these two books on the
screen at the same time. Each book has a it's own browser.
Is it possible to have two separate client sessions for the same
application for the same user? Launching a second browser with a
different session ?

you can't rely on sessions like this. You will have to architect the
application differently. Why not prefix the name of the session
variables?

use cookieless sessions. then the link to the new browser window will create
a new session (fully qualify the url so its is no decorated with the session
id)

Hi Sebastian,

Session variables have a nasty tendancy to time out, and are unreliable for
what you're describing (since you are talking about technical documents that
the reader may keep open for a long time). I would suggest opening the new
window using a QueryString that contains the information you are talking
about storing in Session. Another alternative would be to have the child
window "query" the parent window using JavaScript. In the child window, the
parent window can be referenced in JavaScript as "opener." In other words,
you're probably best off having the windows keep track of one another on the
client side.

If you need to persist this data across PostBacks, you can put it into a
hidden form field on the Page. This can also be done using client-side
JavaScript. Once the Page is posted back, you could even add it to the
ViewState.

Sessions may often seem like the easiest way to do things. However, ASP.Net
is designed with the recognition that Sessions have their drawbacks, and
therefore, includes a number of alternative methods for persisting state.
