session timeout?

[Billy Zhang]

I have a asdp.net app which is form auth.
There is a problem,

The user logins and uses the app, sometimes user will be redirect to the
default login page, why?

Is the session timeout(default 20 mins), but the user is using the app?

Why?

Why?

Check the AppPool recycling settings. This will happen if the pool recycles
whilst in use. Also check the event log for errors or warnings that might
indicate that the pool recycled for unexpected reasons.

Have no any error in eventlog.
But I found the web garden was set as 2.
Maybe this is the cuase why i was redirected to the login page.

Yes. Session state such as the login status will be held per process. Yet
web gardens maintain no session affinity so requests from a client that
logins a user via one process may also end up going to the other process
which isn't aware the user is logged on. Unless you have a really good
reason to use a web garden set it to 1.

Hi Billy,

I think Anthony's suggestion is reasonable and good. It is likely the
process recycle (or the web-garden based multi-process behavior) cause the
user get unmatched forms authenticated ticket between multiple requests.
Actually, one of the most important setting for generating the forms
authenticate ticket and also many other ASP.NET random generated identiteis
is the machine key. By default machine key is auto-generated for each
ASP.NET appdomain. You can also customize it:
