203831 - Mozilla Calendar chokes on webserver response 304 when fetching calendar data

Status: RESOLVED DUPLICATE of bug 203833

(Calendar :: General, defect)

Description

[satmd]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.4a; MultiZilla v1.4.0.4A) Gecko/20030401
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; de-AT; rv:1.4a; MultiZilla v1.4.0.4A) Gecko/20030401

A messagebox pops up telling me that Moz Cal cannot download the data if the
webserver sends a Status 304 (NOT MODIFIED) instead of the file (200).

Reproducible: Always

Steps to Reproduce:
1. Subscribe to any iCal that's located e.g. on a correctly configured Apache
webserver
2. Fetch that iCal multiple times (while server content is not changing)
3. See this messagebox pop up 

Actual Results:  
Nothing. No updates were performed (which is correct after all as the iCal
wasn't updated on the server, too)

Expected Results:  
I expected this to work without that messagebox

There are 2 possibilities to solve this:
1. Filter the 304 server-sideous and make it look 202 (I used two VirtualHosts.
One is proxying the other with "NoCache *") [ I tried this and it works. Ugly
solution.]
2. Just accept an status 304 as an successfull update.
E.g.:
Correct update:
Moz Cal requests update -> Webserver sends file (200) -> update is imported

Problem && solution :
Before: Moz Cal requests update -> Webserver send Status 304 -> Moz Cal cannot
cope with this -> Messagebox
After: Moz Cal requests update -> Webserver send Status 304 -> Moz Cal sees this
as an successful update -> normale operation will continue
