Form Validation/SessionID changes

[Jeff White]

Hi All,
I've got an Asp.Net application, I've set the loginurl to "login.aspx"
and my validation is working fine. However, after I log in and navigate to
"default.aspx" (or whatever page) my session is being reset.

I create and set some session variables during my login procedure and these
are all getting reset. Also, once I try to navigate to any other page
besides the original page, I am prompted to log in again (This second login
does NOT reset my session.)

I was originally under the impression that it would only happen when
navigating to sub-directories, but this is not the case, I've moved
everything into the root.

I have the basics set up in my web.config:
<authentication mode="Forms">
<forms loginUrl="login.aspx"/>
</authentication>
<authorization>
<deny users="?"/>
</authorization>

Any help would be greatly appreciated!

Hi Jeff,

By default, these behavious won't occur with a Form authentication. Would
you please post the code for the login procedure? Additionally, did you
change the Session object's property any where, for example, mode or
cookieless?

Hi Luke,
Here is my login procedure (and accompanying code) I have removed some
of my database code for this forum, if you need to see, please let me know.

I have all session settings at default, and only set any session variables
in the code below.


<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data
source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>

Thanks for your help!

Hi Jeff,

I have studied the code and all of them seems be fine, except that:

FormsAuthentication.SetAuthCookie(UserID.Text, False, "/*")

Normally, we don't need to do this in code. You may remove this line ans
test again to see if this will help.

And here is a good sample for form authentication:

Hi Luke,
Thanks for your replies, they confirmed that my code was mostly right. I
did find a bug in my code where I set my "webaddress" session variable. I
was using a slightly different domain name, which was causing a new session
to be created. I read a posting earlier about a similar issue and didn't
realize I had commited the same error.

Thanks again!
Jeff
