460702 - modified since not working - apparently x'ed out

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

User-Agent:       Opera/9.51 (Windows NT 5.1; U; de)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.17) Gecko/20080829 Firefox/2.0.0.17

It seems that since I updated FF to 2.0.0.17 the modified since does not work any more properly. This results in enourmous transfer time and loading time of pages as all files are downloaded over and over again instead of being used from the cache.
Trace follows.
The trace clearly shows that the same file is requested twice and sent twice, while there is a field of 
XXXXXXXXXXXXXXX: XXXXXXXXXXXX
which seemed to be the modified since.

Reproducible: Always

Steps to Reproduce:
1.Work in Typo3 Backend where a lot of symbols are used multiple times
2.
3.
Actual Results:  
Each symbol (=file) is downloaded on each GET request as the modified-since is not included in the GET request

Expected Results:  
Each file is downloaded instead of being taken from the cache resulting in
* slowing down of creating page 
* increased download amount

1) send the modified since request to the server
2) server response to NOT MODIFIED
2) take file from cache

I have updated today to 3.0.3 and after having worked without this problem, now the proble also occured with 3.0.3

The major issue with this problem is that the traffic will be indreased dramatically and response times slow down.

This is a mass search for Firefox General bugs filed against version 3.0 that are UNCO and have not been changed for 200 days.

After you update, please create a fresh profile, http://support.mozilla.com/kb/managing+profiles, and test to see if your bug still exists. If you still the bug, then please post a comment with the version you tested against, and the problem. If the issue is no longer there, please set the RESOLUTION to  RESOLVED, WORKSFORME.
