One time, I had to prototype that would be relatively stable, yet worked for WebTV web clients and hyper-secure IE/NS browsers.

WebTV doesn't know what cookies are: all Set-Cookie headers are condemned to /dev/null. Ouch. PHP's session-handling functions and Perl's Apache::Session module are both ruled out by spec.... (I missed CGI::Session in this feasibility study.) IE and NS can be configured not to record cookies at all.

I ended up prototyping a DB-based system that relied on both cookies and IP address/web client pairs. If the cookie was verified to work, the fallback system (IP address/web client pair) was disabled automatically.

Another possibility is to explicitly store an index to the session information as a form/URL variable, in the HTML, whose value's validity expires in a reasonable timeframe. The actual information would be stored in a DB backend (cf. prior posts for examples).
