Hello all.

Out of necessity I developed a memcache plugin for shibboleth 1.3 to  
serve as session and replay cache. It's probably very specific to our  
needs here but if there is interest I can submit the code.

Advantages:
- Very fast. Much faster than odbc and not much slower than in-memory  
cache
- No need for sticky sessions on the SP since the cache is shared
- The same cache can be used by various SPs/applications and,  
theoretically, reduce the individual SP's memory consumption. This is  
done adding a prefix to the sessionid so they don't clash.
- Can be configured to generate a map like (SomeAttributeValue ->  
[ SESSIONID1, SESSIONID2]). We use this map when a logout is done at  
our IDP. We fetch this map and delete all the sessions of this  
particular user. Instant global logout. :)
