Users getting logged out and system log entries

web-app

Gemini version 3.5.4 (Build 2435):

We've recently migrated too this version of Gemini but since the migration some users have complained about being logged off of the application unexpectedly - I have witnessed it myself when a user created a new comment and was immediately dumped back at the login screen.

I have also noticed entries (27 so far today) in the system log saying:

No Page.Request.UrlReferrer detected : /gemini/issue/ViewIssue.aspx

At around the same time, the server's application event log contains an entry:

I don't know whether they are related, but can you shed any light or suggest anything?

Cheers,
Nigel.

Can you please check that the Gemini application pool (in IIS) is not recycled too often?

Aslo, please make sure that the full Gemini URL setting is correct. If possible, check the URL after the session expired redirection happens and make sure it is correct.

Gemini application pool recycling is set as per the installation instructions - a dedicated pool for Gemini, recycled in the early hours of the morning.

The URL may be the clue, however. On further investigation, I suspect the users experiencing the problem may be using an out-of-date URL (which still works) to connect to Gemini, but the setting in the application is, at some point, generating a URL using the new root and at that point the user is regarded as not logged in so ends up back at the login page.

If I find any instances where this is not the case, I'll get back to you.

Thanks,
Nigel.

A user has reported seeing these problems again,even after changing the URL they log in on.

He has reported the full URLs before and after the incidents, and they all look fine.

Any other suggestions?

Can you tell if the user has been idle for a long period?
Aslo, try and set Enforce Full URL to "Yes".

Setting "Enforce Gemini URL" is already set to "Yes" (what does that setting do?).

Unfortunately, the user in question is away this week so I can't find out whether he was idle for a time before the issue arose. I'll check with him when he gets back.

By default Gemini will try and find the full url, setting this value to yes will prevent Gemini from doing so.
