Re: Strange Session problem

Hi Jeremy

thanks for the response. Typically I have now found the mistake, after
posting... this tends to happen to me.

Here's what happened. We have an auto-complete input box that uses an
ajax call to find the users in the system. Since this can be used
multiple times, I cached the results in the session, to make
consequent lookups faster. I think what happened is that this was too
big for the session to handle, and so the search criteria never
actually got persisted. This maybe a database thing since I'm using
the database to keep the session information. I removed the learner
session caching and it now works like a charm.

Good to know that http and https could give problems. I'll bear that
in mind when we secure our site a bit more.

Thanks again.
