This is true... and then it's not :-)

If your proxy terminates the HTTPS connection, effectively doing a
"man-in-the-middle" (but controlled by you), it can: most probably
you'd have to fool your browser by offering it a HTTPS connection
from the proxy, and by installing a trusted root certificate you
create yourself. Basically what the proxy in your $CORPORATION does
all of the time.

I don't know whether privoxy or squid can do that (I'd love to know,
mind you, but days are so short).
