It won't cache it. Embedded images will still be treated normally.

The browser will (alas) do whatever the hell it wants, including (but not
limited to): * Caching it.
    * Not caching it.
    * caching it and all the embedded stuff.
    * Not caching it and not caching any of the embedded stuff.

It all depends on the browser and what the user has told it to do.

If the data is a per-user sort of thing try 'Cache-Control: private'
instead of 'pragma: no-cache'. If you really don't want the base page
cached, try 'Cache-Control: no-store' instead of 'pragma: no-cache'. The
'pragma: no-cache' is a deprecated form, I believe.
