[HTTPS-Everywhere] Feedback on HTTPS Everywhere

I'll bite.

Some ISPs (e.g. Comcast) use transparent caching servers to speed up access
to frequently-requested URLs.  Using SSL for these connections precludes
transparent caching, as your ISP (should) never see the full URL for an SSL
request. Instead of responding quickly with a ready-to-go image from a
server on their network, they have to pass the request on up to the original
site.  The original site may be considerably farther away (ping-wise) than
the caching server.  The original site may also experience considerably more
load than your ISPs caching server (serving one batch of clients vs. the
rest of the internet).  SSL connections take longer to set up and tear down
than normal TCP connections (handshaking, key exchange, etc).  All of these
factors add up to a client experience that is slower, but more resistant to
logging and malicious packet injection.  You trade some lost performance for
some gained security.

Side note 1:  "http" DTD references and "http-equiv" headers are not
necessarily insecure URLs.  Please be careful where you point your
highlighter.

Side note 2:  If I remember correctly,* even if a page or HTML document
contains insecure http:// references*, those references will be fetched over
and SSL connection if HTTPS Everywhere has a rule that matches the
reference.  (Example:  If http://www.cnn.com calls for an image from
http://timewarnercdn.net/images/blahblahblah/omgwtfbbqsauce.jpg  and HTTPS
Everywhere has a rule for http://timewarnercdn.net ->
https://timewarnercdn.net, the image *should *be fetched over an SSL
connection. )   In other words, even "insecure" Facebook pictures can
fetched over an SSL connection, albeit at a slower speed (see above).
