page caching since adding vBSEO - not showing logged in on page refresh after login

One strange thing has happened since adding vBSEO -- I notice now if you are logged out and you login via the standard vbulletin navbar login forum you are returned to a page that still shows you logged out on the top navbar... if I click the browser's refresh button all is well, so it appears with the addition of vBSEO or maybe just from the url change (?) the browser is now caching pages (excessively) when the login change at the top (login password blank vs. welcome username, etc.) should be producing a different page... I'm afraid this new page caching may confuse users who think there is a login issue. I do not see this with vBSEO disabled. Anyone else see this? Is it a setting in vBSEO I'm missing?

This doesn't happen with my site. What version are you using? Are you using any kind of caching hacks?

vbSEO RC8.
No Caching Hacks on the server.
Seeing it in latest Opera 9.10 browser. Will test with other browser shortly.

Maybe it's my ISP doing something strange with caching because of vBSEO URL's now.

Does it happen in Firefox or IE? It may be an Opera issue. I don't use it so no help there.

Seems to be a glitch with the Opera Browser and vBSEO. It doesn't happen with Firefox. It doesn't happen with Opera on the forum homepage. But it does happen with Opera on any of the vBSEO re-written URL show forum or show thread pages. It doesn't happen with Opera with vBSEO off. Not too many people use opera, so maybe not a big issue.
