200698 - HTTP header is sometimes displayed in window

Status: RESOLVED DUPLICATE of bug 197426

(Core :: Networking: HTTP, defect)

Description

[Anthon Pang]

User-Agent:       Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.3) Gecko/20030312

Seems to be more likely when visiting a page for the first time.  Viewing the
page source, the header is not present in the text.  Reloading the page cleans
up the display.  No pipelining.  I thought it might be related to link prefetch
being enabled, but I wasn't able to reproduce after clearing the cache and
restarting Mozilla.

The HTTP header appears to be malformed, i.e., leading "0", eg,

0 HTTP/1.1 200 OK Age: 0 Transfer-Encoding: chunked Date: Fri, 04 Apr 2003
18:24:53 GMT Content-Type: text/html X-Pad: work around browser bug Server:

Related to (duplicate of?) bug 184528 and bug 194642.

sounds like a duplicate of bug 195746.  please try out moz 1.4 alpha.

reopening based on bug 195746 comment #38

i wonder if this has anything to do with the proxy server mentioned in this header:

  Via: 1.1 nwmrbc01wc03 (NetCache NetApp/5.3.1R2D2)

reporter: can you try browsing without the proxy server?  is that an option for you?

I can't bypass it -- I'm on ADSL and my browser proxy preference is already set
to "Direct connection to the Internet".

Apparently my telco/ISP uses these net appliances upstream (ref:
http://www.netapp.com/products/netcache/software_specs.html).  I've deduced that
the netapp name "nwmrbc01wc03" refers to "New Westminster, British Columbia",
while something like "vancbc01wc02" refers to "Vancouver, British Columbia".

I've started running WinPCap and Ethereal to see if I can shed more light on
this, but it's plausible that NetCache is contributing to the observed problem.

if you could enable mozilla's HTTP logging that would be best.  here's what to do:

open up a DOS prompt and type:

C:\> set NSPR_LOG_MODULES=nsHttp:5
C:\> set NSPR_LOG_FILE=C:\log.txt

then run mozilla from the DOS prompt like so:

C:\> cd \path\to\mozilla
C:\path\to\mozilla\> .\mozilla.exe

now try to reproduce the problem.  once you have exit mozilla and either upload
log.txt to this bug report or send it directly to me via email.  thx in advance!

NOTE: the log file may grow very large.
