My choice was to put a "confirmation" field in the database, and put 
this field (randomly generated) instead of the continuation in the mail. 
Thus, the user can validate is account whenever he wants. And I've got 
no continuation left in memory.

Waw. You should have a lot of memory ;) Or very few users :p

I don't really know. We were thinking it was a good practice to not 
over-use the memory by keeping needless things while we could put these 
in the database, in a same place who can resist to a crash of the machine.
