We have exactly the same problem here with sites being both inside and
outside. However, I'm happy to take the performance hit until I have to look
at SSL acceleration cards. I need to get hold of one, however since my line
manager doesn't understand the problem they are supposed to solve persuading
him to allow me to obtain one is proving difficult. I wonder sometimes if he
actually understands what I do all day...

But I digress as ever. IMHO it would be useful to add data to the SSL stream
that isn't strictly classified as it just makes it harder for anyone to
obtain classified data even if they use brute force decryption. Whilst 40/56
bit browsers abound it's probably worthwhile.

Of course, if speed is an issue I'd seriously look at SSL acceleration. At
the very least get hold of a card and benchmark it (which is what I intend
to do, one day soon). I've noticed a substantial drop in speed when IE is in
use. Why Microsoft have been unable to implement SSL properly after having
so much time is beyond me. I shudder to think what painful hacks are in
place with IIS in order for IE and SSL to work.

Subject: Mixing SSL and non-SSL content - request for comments


I guess I started this debate so perhaps we can widen it my making it
more general and hopefully come up with a general solution...

The issue is the following: Suppose I have a site which receives and
transmits sensitive user data. Obviously, I want to protect it with SSL.
However, 90% of the content of the site is GIF which doesn't really need
to be encrypted (logos, navigation-bars etc.) Now, if the whole
DocumentRoot is under SSL, these rather large, GIF files will be
laboriously encrypted and decrypted in the course of the transfer even
though they contain unconfidential information (it's just the same GIF
that's on my unsecured home-page!).

Question 1: Should we worry about this at all? (my manager was worried
about the load and so felt that we should).

My solution to (1) was to use mod_rewrite [see footnote] to serve the
pages from a plain HTTP VH. However, as James Treworgy points out, this
leads to all sorts of unfriendly warnings in the browser.

Question 2: Is anyone aware of a general solution for this "problem" -
i.e. how to serve selected components of an SSL page via plain HTTP.

Best regards,

owen Boyle.
