59238 - in NS6, this url doesn't reload when it should

Status: VERIFIED WONTFIX

(Core :: Networking: HTTP, defect)

Description

[Kathleen :Brade]

this is blocking bug #55914

I can't load this url on Macintosh:
  http://166.90.144.66/cgi-bin/nph-dtspush.cgi?camera=jpeg/surfline04/
cam0.%%08ld.rgb888.enc

Others ([e-mail]) haven't been able to load this url on Linux.
It loads fine on 4.x (at least initially that is).

Expectation: Page should load or I should get some kind of dialog/message telling 
me why it couldn't load.

The problem here is a bogus URL.  "%%" is not a valid encoding for the "%"
character in a URL.  Changing the URL to:

http://166.90.144.66/cgi-bin/nph-dtspush.cgi?camera=jpeg/surfline04/cam0.%2508ld.rgb888.enc

(note the %25 instead of %%) makes it work in Mozilla for me...

fixing url above; thanks [e-mail]!

Changing summary in case what I am seeing is a bug... I don't see this document
ever reload...  I think to test/confirm 55914, we need this url to reload.

Pam--can you confirm the expected behavior for this url?

If I just go to the page, it does not reload.

If I go to the page and then hit the reload button, it starts reloading over and
over again (this I assume is the intended behavior).  Same if I hit C-r.

This is not a cache issue; I have tried all three cache settings (validate
always/once/never) and I see the same behavior for all.

win98 200110604 trunk - the inital page never breaks connection to server, but
image is NOT reloaded the image.

Reloading the page startes loading the image all the time, too fast even so I
can't make out the image

Is this the same bug, or something completely different ?
This morning I add a little bit of text to
  http://piclist.org/techref/microchip/compcon.htm?edit
and hit the ``update'' button.
(um... you won't be able to see the edit field, sorry. Do I need to get
a special Bugzilla account set up ?).
Later I go to page
  http://piclist.org/techref/microchip/compcon.htm
and hit the ``edit'' button which returns me to the same URI,
  http://piclist.org/techref/microchip/compcon.htm?edit
.
I expect Mozilla to load the current text, including the stuff I added this
morning. Unfortunately, I see yesterday's text (from the Mozilla cache), so when
I make a few changes and hit ``update'', these changes are saved, but the text I
added this morning is lost forever. Oops.
Workaround: every time I go to page
  http://piclist.org/techref/microchip/compcon.htm?edit
I hit the ``refresh'' button, which loads in the current text. Then I can make
changes and hit ``update'' without loading anything.

Late breaking news:
I *thought* that sticking the question mark (``?'') in the URI indicated
``don't cache me'', but
http://www.w3.org/DesignIssues/Axioms.html
specifically says it *is* OK to cache all URIs, even those that include the
question mark.

So this annoyance is really part of Mozilla's standards compliance.

Is this an issue with relnoting?

dcary: if you want to prevent caching, you HAVE to use headers; there is much
information from http://www.squid-cache.org if you look.

Basically, set expires: to now, and last-modified to now, and maxage and
s-maxage to 0.

If you're using PHP:

Header("Cache-control: must-revalidate maxage=0, s-maxage=0") should do it for you.

Comment 9

[Darin Fisher]

Header("Cache-control: must-revalidate, maxage=0, s-maxage=0")

make sure you include all the commas ;-)

Is this still an issue ?
The testcase is dead...
