The only really big difference as far as I can tell, is the cookie, which is what I'd guess is the issue, but I'm not the kind to send his car to the mechanic and diagnose the issue :)

Reproducible: Always

Steps to Reproduce:
Log in to my school's blackboard installation (sorry)
request https://myasucourses.asu.edu/branding/themes/MyASU_RC1.5/theme.css?v=9.0.539.0 in either Firefox or Rekonq

Actual Results:  
Rekonq isn't given any content, whereas firefox is.
Comment 1 Dawit Alemayehu 2010-08-27 07:14:36 UTC 
Versions please ? Qt , KDE and ReKonq ?? Oh and ReKonq does not use kwebkitpart at all since it is not a KParts based application ; so i am not sure why you reported this against kwebkitpart. Perhaps you wanted kdelibs/kdewebkit ? That is the library used by both kwebkitpart and reKonq. 

Anyhow the issue here might be missing cookies or the server serving different content based on useragent string, or even a bug somewhere. However, we cannot being to help you narrow down the problem until you provide some of the information requested above.

What would help greatly with narrowing down the causes is to install both the Arora web browser and kwebkitpart (extragear/base/kwebkitpart) for Konqueror and see if you can reproduce the problem.

Hi dawit thanks for the feedback..

The version is compiled SVN from about three hours ago of my entire kde stack, rekonq included.. My apologies for not filing against the correct component, I didn't realize kdelibs had a webkit component... I'm reassigning as this issue does occur in konqueror's kwebkitpart from the same trunk and does NOT occur in Arora 0.10.2

I am sure this issue is also related to the caching related bug in kio_http. Can you please disable caching and try to see if this problem goes away for you ?
Comment 4 Dawit Alemayehu 2010-11-23 22:52:06 UTC 
Marking this a duplicate of 256104 because another blackboard related website had the same issues that was caused by kio_http's caching problems.
