Hi Ted, I was just having a very similar discussion off-list with someone else.
Where you crawled by a search engine(s) this morning? These kinds of entries are normal, but an "excessive" amount can point to one or two things: ----------- ~~ Search Engines normally do not (or care about) the ability to store cookies and the UserReference key used for managing User Scope variables is a "session-cookie". Witango typically issues these keys automatically. So "each page" crawl from an Engine is just like a new visitor to your site. Each crawl is typically issued a new UserReference key. This is normal behavior, and there is nothing wrong with this (other platforms like PHP and ASP also use session-cookies this way) - but it's also a good reason to not assign too many User Scope variables unnecessarily. As a rule, I only assign a User Scope variable if I have a "very" good reason to. Note: the same above behavior can also come from robot scripts attacking a website. ----------- ~~ The other reason could be that something in your code is preventing the Witango server from issuing the keys properly in a managed fashion, and the fall back behavior of the Server is to keep issuing new ones (if the previous ones are going missing). This can happen if you have any custom local$httpHeader variable assignments that don't also include <@userreferencecookie>, or use it properly. --- The [Expired], in your logs, comes from when these previously used session-cookies go unused for whatever your default expiry time is (default is 30 minutes). Open your log file in a text editor, select one of the expired key values lower down in the file - then search "up" to see how many times that key was used. This can help point to your problem (if any). --- Do your Users sometime loose their sessions (User variables)? Let us know, otherwise I hope this helps. Cheers...
