[imp] documentation about cookie/authentication

[Jie Gao]

Hi All,

I'm looking at imp-3.2.2 on horde-2.2.4
---------------------------------------

Can somebody explain, just briefly and to save me (possibly a lot
others) some time trying to figure this out, what the HORDE and IMP_KEY
cookies do in relation to authentication and session management?

It seems to set the HORDE cookie at every access, and set the IMP_KEY
at logout.

Thanks very much,



Jie
