Hi,
I found a bug in IE6, though it is known already. If I have a CSS
background property set to some image, such as
background:url( myimg.gif);, and I apply this property to some html
element, say DIV, and refresh DIV every 10 seconds, background image
is reguested every 10 seconds for IE6, too.
The fix which I found did not fix the problem:
try {
document.execCo mmand("Backgrou ndImageCache", false, true);
} catch(err) {}
Relative info: http://www.mister-pixel.com/#Content...is_that_simple http://dean.edwards.name/my/flicker.html http://www.fivesevensix.com/studies/ie6flicker/
What's the known workaround? 4  4231

It seems to work for me. I have this in many of my site js files:
// Turn on background image caching in IE
// --------------------------------------
/*@cc_on
if (document && document.execCo mmand) {
try { document.execCo mmand("Backgrou ndImageCache",f alse,true); }
catch (e) { }
}

Hmmm... Maybe it works, but my access.log file in Tomcat shows these
images are requested every time. How do you know if it works for you?
Thanks.

Additional word. It solved the problem (with JS or server
configuration) by sending HTTP 304 (not modified) instead of earlier
200 (request ok). But I do not to see those requests at all. How
possible is it?
The most effective way to solve this problem (and improve the
performance of your application at the same time) is to apply caching
header directives. All images should have a caching header indicating
when the image should expire from the cache. With this header IE will
cache the image and not continually make requests over and over.
Tomcat does not have the ability to do this out of the box. I
actually just finished a release of a little Tomcat/J2EE app server
plugin (a filter) that makes this very easy to do. You can take a look
and download Resource Accelerate at http://www.xucia.com/#Resource%20Accelerate.
This should apply caching headers for you and fix your multiple
request problem.

Hi all,
I am using a background image via a stylsheet.
I've used this code: background-image:url("/images/tile.gif"); (which
I think is correct)
The image doesn't show up however, the path, the filename etc etc,
everything checks out ok.

Hi there,
I need to use a background image in a TR that does NOT restart
everytime it hits a TD. Can it be done?
Specifically, if you set a background image for an entier table, now
mater how many TRs and TDs you have, it will show the
complete/unfragmented image (as long as you don't over-ride it).
When I set a TR background image, every time I hit a TD it "re-seeds"
the image. I want to have a TR that shows an 800px image in it's

Hello,
I'm sure this has come up before. I have need for a collection of all
elements/objects in an HTML document that have any kind of an
attribute (HTML or CSS) that is making use of a URL to display an
image. document.images only seems to reference image tags. The
collection needs to include background images, input type = image,
image maps, css assigned background, etc. Honestly, I am probably not
aware of all the possibilities...

I am trying to implement an image map (in this particular case a
country map) with few <area ...>s on it.
The challenge is to add background image (dot) to each <areaso it
will display over the image map.
I am failing miserably at that.
Anybody tried to do that before?
Anybody succeeded?

Hi, all.
Need help with what seems to be either connection, or threading problem in
my ASP.NET 2.0 application.
The gist of the problem is this: IHttpHandler in my application serves an
HTML page that has two images (image A and image B) in it. Once the HTML page
is served, expected behavior is this:
1) receive request for image A,
2) receive request for image B almost at the same time as for A,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
