I'm using a single css for 3 different layouts in my site, where everything
is the same, but header images. Recently I've run a "download times" test
and it turned out that my css is calling the 3 images every time a file is
opened, increasing total download time, even though only one header image is
actually appearing on that page.
So, is this really happening when a user opens a single page? Should I
better have 3 stylesheets instead of only one?

interesting, although i think that most modern browsers only download
those images that are actually used in the <body>. but you could stretch
your test including 1000 images (some very large images) in your css and
none or 1 in your body.

Please be more specific about this "download times test". Is it
monitoring the operation of some real browser (if so, what browser was
it?), or is it some self-contained utility which is simply retrieving
every URL that it can find? If the latter, then it might be that a
real browser would behave differently.
In any case, *even* if all 3 images were being retrieved, then so long
as your images are being sent out with proper cache validator
information, then any normal browser would be cacheing them on first
retrieval, and they'll do little harm thereafter.
Should I better have 3 stylesheets instead of only one?
I don't think there's a hard and fast answer to that one - "it
depends". Can the reader start browsing the page while the image(s)
are still being retrieved? It can be very annoying, on the *first*
visit to a page, being made to wait while extraneous decorations are
being retrieved, *before* the browser is willing to display the
substantive content. It's even *more* annoying if this happens on
*every* visit to the same page (as seems to happen with some
poorly-designed systems for dynamically building pages at the server,
but presumably we're not dealing with such a system in your case).
(I'd surely want to take a look at optimising the file size of the
images, regardless of these considerations. )

Are you by chance using IE6 SP2 (and maybe earlier releases). Check this
against a non IE browser and see how many times the images are being called
from the server. It may_not_ be relevant, but you could be suffering from
some M$ marketing strategy.

Without an URL demonstrating the problem, we can only off WAGs.

Thanks everyone for your thoughts. Until now I would think that you could
have more information using the tool I talked about last time: http://www.websiteoptimization.com/services/analyze/
Alan,
Cache, images and overall layout are all optimized for maximum accessibility
and quick access, so visitors *can* view the page fairly fast. That's not
the problem, but thanks for pointing to it.
As Jimbo sugests, it may be only a trick... This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

When a user downlaods a file from my website I want to track how many times it has been downloaded. When the user clicks on the link I can simply redirect to a page recording how many times this has been downloaded before the download starts, but is there a way to record how many times the download is completed? I think it will need to be server based, as I don't know how to check if download is complete any other way?
