For more fun; if you're serving Zope behind Apache (at least using PCGI) the bug does not occur. I've seen this for far older versions of Zope too; I've run into this type of netscape/ZServer weirdness in earlier 2.2.x versions at least. So I suspect this is not a new bug. Not sure if it's Zope or Netscape that's doing something wrong, either. > Again, this was not a problem pre 2.3.0 b3 / release... Again, I think it was -- I've seen it before.

A couple of times I've seen it blow up the server logs; I suspect a netscape left open to our site in a computer lab somewhere.

We'll now be writing something that parses and replaces the CSS with the CSS source for the Mozilla/4 clients.

Re: [Zope-dev] 2.3.0 release badness
Does the same occur if you serve using something else ('DTML Method',
'File', 'ZStyleSheet' etc)
I have noticed problems with Netscapes handling of Text/CSS stylesheets. It
appears that long or particularly complex stylesheets that can be (And here
is the kicker) downloaded too quickly, do not seem to complete correctly and
for me they have even resulted in Netscape locking up (Linux and Win32).
Admitedly, my stylesheets were HUGE! :) - I was trying to break my
ZSytleSheet product and was browsing the sheet using Netscape on the server.
I don't know if this is related...

It seems to occur on Unix versions only AFAIK. When you visit a page with linked CSS, visit another page, and come back, sometimes a portion of the page is replaced with the text of the CSS.

This is a known bug in Netscape. The management interface does user-agent sniffing; "Mozilla/4*" that doesn't contain the string "MSIE" embeds the style while all other user-agent strings link the CSS instead. You'll notice that if you "view source" on MSIE, the CSS is linked rather than embedded. Perhaps you can use the same strategy. It's done in DTML.

I have had the same issue in all of the 2.3.0x Zope versions, and the problem is not really Zope but Netscape 4.X. For me, the trouble arises once in a while and specially when I start doing page reloads quickly. It seems that, when Zope starts serving the document, Netscape asks for the stylesheet file almost instantly (because it is inside the HTML's header) and then a sort of synchronizing error happens. When you are at the local machine the delay between the document requests is larger so the problem is less frequent. I have never seen the problem under Netscape 6 or Mozilla. I don't know to what extent this could be Zope's fault.
