Insert new parameter to value column of sessions table

[tblanchard]

Hello,

We are trying to add a new parameter to the "value" column of the "sessions" table.

We see that the contents of the "value" column is serialized, and appears to be in an array.

Is there a fairly simple way to add our own new parameter to the bunch?

For example:
$newparam = "true";

We're just trying to flag certain visitors using a cookie, but when switching into shared ssl, we lose that cookie because we're on the shared ssl domain at that point.

If we could store that "$newparam" in the customers session, we could give them a new cookie from the shared ssl domain and solve our problem.

Any help would be greatly appreciated...
