Session cache and Global filter.

Hello,
session.gc_maxlifetime = 200000
session.cookie_lifetime = 2000000
I tried absolutely everything storage mechanisms. Now I use "via their IP address".

If we use others, when approaching the site by anonymous, meaning global filter is reset by default when changing to another page. If it is selected "on the server, as a small file".

Tried all the different settings. Always or problem with the disappearance of the list of cities, or a problem with transitions to other pages (global filter takes the default value)

I installed the previous version of the module - everything works fine with default settings.

I'm sorry, I hurried. The problem remains, but it has proved itself through a later date. And then I have hoped ....

In fact of the matter is that I do not do anything on the site during this time. Just after a while I go and see this problem. At what time after which this problem occurs is always different. Can work out all day, and maybe a few minutes does not work.

Site only in development. Not visited. But sometimes it comes to the casual visitor. There is a suspicion that the problem occurs when you visit the site by other users. If this can be a problem... Although it happens right while on the site appears this problem.

Added to page.tpl.php string drupal_flush_all_caches ();
Workaround. Site slow, which is understandable.

I'm afraid to jinx it, but the problem seems to be solved.
Sorry, the problem was on my side. The fact that the long-developing this site, I uploaded it to a test domain. Later, I moved the site to another domain, forgetting to remove the old. So I worked two sites on the same basis. On the test site has not been selected the city. I believe that when a visitor came to the test site, it is cached, A new site being loaded on the same cache as the base was one. Completely remove the test site and the problem was resolved. Once again I am sorry. Thanks.
