I have a customer who is blaming our Redhat Linux server 9.0, with Apache 1.3.31 server for a caching problem.

The customer is using XML to provide menu buttons that change when moused over. They work fine when using Mozilla (Firefox) and Opera. But, with IE, there is a delay between the images displaying each time and it shows a blank for a moment before it shows the rollover image.

Are there any known issues with Internet Explorer or Linux/Apache in regard to this issue?

Thanks.

Verify that the IE browser gets the freshest datafrom the server by hitting the F5 button.

Sound slike an IE problem...

Not sure if this will help at all, but you can try reading this:

I retrieved this from the client site. Wouldn't using a full URL cause this problem of delayed images? Doesn't using a full URL rather than a relative link force the browser to download the content each time, or am I wrong?

Found The Solution

Found this link that shows how to solve this IE rollover image problem on Apache.

In case the link doesn't work for you, this is what you do...

===========================
If you get a flicker problem in IE< then you can fix this by adding the following lines to httpd.conf (Apache)
===========================

-----------------------------------------------------------------------------------------------
<IfModule mod_setenvif.c>

# the lines below stops screen flicker in IE
BrowserMatch "MSIE" brokenvary=1
BrowserMatch "Mozilla/4.[0-9]{2}" brokenvary=1
BrowserMatch "Opera" !brokenvary
SetEnvIf brokenvary 1 force-no-vary

</IfModule>

Make sure the rollover images are being preloaded in the head tag or in the body tag.

Otherwise when the user rollsover the delay could be loading the image.
