    <p>I'm at a loss here. I've got a specific group of users upstairs whose sessions seem to expire completely randomly. It's not just when they leave the site sitting for a while, it can expire while they're browsing around. For me and most of our users everything works just fine. It's not a browser issue, we've got people in FF and all IE versions that both function correctly, and people in FF and IE that don't work.</p> <p>My <code>gc_maxlifetime</code> is at <code>43200</code> and the garbage collection is a crazy low <code>1/1000</code> (not that that should matter). Is it possible there's something else running on the server that's randomly deleting some of our sessions? What should I check? That still wouldn't explain why only this specific group seems to be affected.</p> <p>I have a few Session settings that are different from the default:</p> <pre><code>session.gc_maxlifetime = 43200 session.gc_divisor = 1000 session.save_path = /var/lib/php/session session.use_only_cookies = Off session.bug_compat_42 = Off </code></pre> <p>The first three I'm not worried about, but could the last two be causing this behavior? I don't actually ever send cookies through the URL, so I have no good reason for having use_only_cookies off. I have no guarantees that the misfits who made this app before I got here didn't exploit the <code>bug_compat_42</code> thing to set session variables, but again, I would expect an issue with that to be less random.</p> <p>Edit:</p> <p>On further investigation, I've found that the Session is not being destroyed at all, but the end-user is getting a new session ID. The old session still exists intact on the server, but a new one is randomly started while they're browsing.</p>

    1. COOne of two things is happening: the session file on the server is being deleted, or the session cookie is expiring. I'd try to isolate a case of one or the other happening, and then work from there.

    2. COI've determined that it's not the session being deleted. How can I check whether the cookie is expiring?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
